After reaching the end of a gzip stream in the input, gzread will continue
|
||||
to read, looking for another gzip stream, or failing that, reading the rest
|

len.

||||
to read, looking for another gzip stream. Any number of gzip streams may be
|
||||
concatenated in the input file, and will all be decompressed by gzread().
|
||||
If something other than a gzip stream is encountered after a gzip stream,
|
||||
that remaining trailing garbage is ignored (and no error is returned).
|
||||
|
||||
gzread can be used to read a gzip file that is being concurrently written.
|
||||
Upon reaching the end of the input, gzread will return with the available
|
||||
data. If the error code returned by gzerror is Z_OK or Z_BUF_ERROR, then
|
||||
gzclearerr can be used to clear the end of file indicator in order to permit
|
||||
gzread to be tried again. Z_OK indicates that a gzip stream was completed
|
||||
on the last gzread. Z_BUF_ERROR indicates that the input file ended in the
|
||||
middle of a gzip stream. Note that gzread does not return -1 in the event
|
||||
of an incomplete gzip stream. This error is deferred until gzclose(), which
|
||||
will return Z_BUF_ERROR if the last gzread ended in the middle of a gzip
|
||||
stream. Alternatively, gzerror can be used before gzclose to detect this
|
||||
case.
|
||||
|
||||
gzread returns the number of uncompressed bytes actually read, less than
|
||||
len for end of file, or -1 for error.

This code is a modified version of crypting code in Infozip distribution
|
||||
|
||||
The encryption/decryption parts of this source code (as opposed to the
|
||||
non-echoing password parts) were originally written in Europe. The
|
||||
whole source package can be freely distributed, including from the USA.
|
||||
(Prior to January 2000, re-export from the US was a violation of US law.)
|
||||
|
||||
This encryption code is a direct transcription of the algorithm from
|
||||
Roger Schlafly, described by Phil Katz in the file appnote.txt. This
|
||||
file (appnote.txt) is distributed with the PKZIP program (even in the
|
||||
version without encryption capabilities).

If you don't need crypting in your application, just define symbols

||||
NOCRYPT and NOUNCRYPT.

This code support the "Traditional PKWARE Encryption".
