Function Documentation

strip_fs_prefix()

char * strip_fs_prefix

(

char *

path

)

Strip the file system prefix from a path.

Removes the file system prefix (such as ":/") from the provided path string.

Parameters

path	The path from which to strip the prefix.

Returns

A pointer to the path without the prefix.

file_basename()

char * file_basename

(

char *

path

)

Get the basename of a path.

Returns a pointer to the basename (the final component) of the provided path.

Parameters

path	The path from which to get the basename.

Returns

A pointer to the basename of the path.

file_exists()

bool file_exists

(

char *

path

)

Check if a file exists at the given path.

Checks if a file exists at the specified path.

Parameters

path	The path to the file.

Returns

true if the file exists, false otherwise.

file_get_size()

int64_t file_get_size

(

char *

path

)

Get the size of a file at the given path.

Returns the size of the file at the specified path in bytes.

Parameters

path	The path to the file.

Returns

The size of the file in bytes, or -1 if the file does not exist or an error occurs.

file_allocate()

bool file_allocate	(	char *	path,
		size_t	size )

Allocate a file of the specified size at the given path.

Creates a file of the specified size at the provided path. The file is filled with zeros.

Parameters

path	The path to the file.
size	The size of the file to create in bytes.

Returns

true if the file was successfully created, false otherwise.

file_fill()

bool file_fill	(	char *	path,
		uint8_t	value )

Fill a file with the specified value.

Fills the file at the given path with the specified byte value.

Parameters

path	The path to the file.
value	The value to fill the file with (byte).

Returns

true if the file was successfully filled, false otherwise.

file_has_extensions()

bool file_has_extensions	(	char *	path,
		const char *	extensions[] )

Check if a file has one of the specified extensions.

Checks if the file at the given path has one of the specified extensions.

Parameters

path	The path to the file.
extensions	An array of extensions to check (NULL-terminated).

Returns

true if the file has one of the specified extensions, false otherwise.

directory_exists()

bool directory_exists

(

char *

path

)

Check if a directory exists at the given path.

Checks if a directory exists at the specified path.

Parameters

path	The path to the directory.

Returns

true if the directory exists, false otherwise.

directory_create()

bool directory_create

(

char *

path

)
