GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates the terms
and conditions of version 3 of the GNU General Public License, supplemented
by the additional permissions listed below.
0. Additional Definitions.
As used herein, “this License” refers to version 3 of the GNU Lesser General
Public License, and the “GNU GPL” refers to version 3 of the
GNU General Public License.
“The Library” refers to a covered work governed by this License, other than
an Application or a Combined Work as defined below.
An “Application” is any work that makes use of an interface provided by the
Library, but which is not otherwise based on the Library. Defining a subclass
of a class defined by the Library is deemed a mode of using an interface
provided by the Library.
A “Combined Work” is a work produced by combining or linking an Application
with the Library. The particular version of the Library with which the
Combined Work was made is also called the “Linked Version”.
The “Minimal Corresponding Source” for a Combined Work means the Corresponding
Source for the Combined Work, excluding any source code for portions of the
Combined Work that, considered in isolation, are based on the Application,
and not on the Linked Version.
The “Corresponding Application Code” for a Combined Work means the object code
and/or source code for the Application, including any data and utility programs
needed for reproducing the Combined Work from the Application, but excluding
the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License without
being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a facility
refers to a function or data to be supplied by an Application that uses the
facility (other than as an argument passed when the facility is invoked),
then you may convey a copy of the modified version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the function or
data, the facility still operates, and performs whatever part of its
purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of this
License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from a header
file that is part of the Library. You may convey such object code under terms
of your choice, provided that, if the incorporated material is not limited to
numerical parameters, data structure layouts and accessors, or small macros,
inline functions and templates (ten or fewer lines in length),
you do both of the following:
a) Give prominent notice with each copy of the object code that the Library
is used in it and that the Library and its use are covered by this License.
b) Accompany the object code with a copy of the GNU GPL
and this license document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that, taken together,
effectively do not restrict modification of the portions of the Library
contained in the Combined Work and reverse engineering for debugging such
modifications, if you also do each of the following:
a) Give prominent notice with each copy of the Combined Work that the
Library is used in it and that the Library and its use are covered
by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and
this license document.
c) For a Combined Work that displays copyright notices during execution,
include the copyright notice for the Library among these notices, as well
as a reference directing the user to the copies of the GNU GPL
and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form suitable
for, and under terms that permit, the user to recombine or relink
the Application with a modified version of the Linked Version to
produce a modified Combined Work, in the manner specified by section 6
of the GNU GPL for conveying Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time a
copy of the Library already present on the user's computer system,
and (b) will operate properly with a modified version of the Library
that is interface-compatible with the Linked Version.
e) Provide Installation Information, but only if you would otherwise be
required to provide such information under section 6 of the GNU GPL, and
only to the extent that such information is necessary to install and
execute a modified version of the Combined Work produced by recombining
or relinking the Application with a modified version of the Linked Version.
(If you use option 4d0, the Installation Information must accompany the
Minimal Corresponding Source and Corresponding Application Code. If you
use option 4d1, you must provide the Installation Information in the
manner specified by section 6 of the GNU GPL for
conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the Library side by
side in a single library together with other library facilities that are not
Applications and are not covered by this License, and convey such a combined
library under terms of your choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based on
the Library, uncombined with any other library facilities, conveyed under
the terms of this License.
b) Give prominent notice with the combined library that part of it is a
work based on the Library, and explaining where to find the accompanying
uncombined form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions of the
GNU Lesser General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Library as you
received it specifies that a certain numbered version of the GNU Lesser
General Public License “or any later version” applies to it, you have the
option of following the terms and conditions either of that published version
or of any later version published by the Free Software Foundation. If the
Library as you received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser General
Public License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide whether
future versions of the GNU Lesser General Public License shall apply, that
proxy's public statement of acceptance of any version is permanent
authorization for you to choose that version for the Library.

# libcurlwrapper
This library loads CURL from an Aroma Module instead of statically linking it to the binary. This results in a much smaller binary size (saves about 750KiB).
- Requires the [CURLWrapperModule](https://github.com/wiiu-env/CURLWrapperModule) to be running via [WUMSLoader](https://github.com/wiiu-env/WUMSLoader).
- Requires [wut](https://github.com/devkitPro/wut) for building.
- Use with curl 7.84.0 headers, other versions might not be compatible.
- See important changes in the Usage section.
Install via `make install`.
## Usage
Make sure to define this in your Makefile:
```
WUMS_ROOT := $(DEVKITPRO)/wums
```
Use the normal curl headers, but link against `-lcurlwrapper` instead. For example replace `-lcurl -lmbedtls -lmbedx509 -lmbedcrypto -lz` with `-lcurlwrapper`.
**If the CURLWrapperModule is not loaded `curl_global_init` will return a negative value.**
## Changes compared to normal CURL
libcurlwrapper tries to be a drop-in replacement for libcurl, but some things need to be considered.
### All function are only available between calling `curl_global_init` and `curl_global_cleanup`.
Even functions like `curl_version` only work after calling `curl_global_init`.
### Calling `curl_easy_init` will automatically add CA certificates.
It `curl_easy_init` returns success, `curl_easy_setopt(curl, CURLOPT_CAINFO_BLOB, &blob);` with current CA certificates will be called.
These CA certificates are coming from the modules and can be updated in the future.
### CURLOPT_SOCKOPTFUNCTION
- The `CURLOPT_SOCKOPTFUNCTION` callback requires a workaround to work properly.
- This is caused by `setsockopt` not being compatible with the sockets from the CURLWrapperModule.
Currently, there are two options to get the correct `setsockopt` function:
#### Option 1: CURLOPT_SOCKOPTDATA
- To get a pointer to the correct `setsockopt` function, you have to set the `CURLOPT_SOCKOPTDATA` to 0x13371337.
- The `0x13371337` will be replaced with a pointer to the correct `setsockopt` function.
Example:
```C
static int initSocket(void *ptr, curl_socket_t socket, curlsocktype type) {
int r;
// If ptr is not our magic value, it got replaced with a pointer to a valid setsockopt function.
if ((uint32_t) ptr != 0x13371337) {
r = reinterpret_cast<decltype(&setsockopt)>(ptr)(socket, SOL_SOCKET, SO_WINSCALE, &o, sizeof(o));
} else {
r = setsockopt(socket, SOL_SOCKET, SO_WINSCALE, &o, sizeof(o));
}
return r == 0 ? CURL_SOCKOPT_OK : CURL_SOCKOPT_ERROR;
}
[...]
// Set socktopt data to a magic value to get a pointer to the correct setsockopt function.
curl_easy_setopt(curl, CURLOPT_SOCKOPTDATA, 0x13371337);
curl_easy_setopt(curl, CURLOPT_SOCKOPTFUNCTION, initSocket);
```
Downside of this option: the data pointer of `CURLOPT_SOCKOPTFUNCTION` can not be used.
#### Option 2: curlwrapper_setsockopt
This lib exposes the function `curlwrapper_setsockopt` which will call the correct function. Because this lib had no headers, you have to
declare it in your app like this:
````C
int curlwrapper_setsockopt(int sockfd, int level, int optname, const void *optval, socklen_t optlen);
````
When using C++, you have to add `extern "C"` at the start.
Downside of this option: Linking to the original libcurl fails because `curlwrapper_setsockopt` is only defined in this wrapper lib.
## Use this lib in Dockerfiles.
A prebuilt version of this lib can found on dockerhub. To use it for your projects, add this to your Dockerfile.
```
[...]
COPY --from=wiiuenv/libcurlwrapper:[tag] /artifacts $DEVKITPRO
[...]
```
Replace [tag] with a tag you want to use, a list of tags can be found [here](https://hub.docker.com/r/wiiuenv/libcurlwrapper/tags).
It's highly recommended to pin the version to the **latest date** instead of using `latest`.
## Format the code via docker
`docker run --rm -v ${PWD}:/src wiiuenv/clang-format:13.0.0-2 -r ./source -i`
