Detailed Description

Function Documentation

vlc_fopen()

FILE * vlc_fopen	(	const char *	filename,
		const char *	mode )

Opens a FILE pointer.

Parameters

filename	file path, using UTF-8 encoding
mode	fopen file open mode

Returns

NULL on error, an open FILE pointer on success.

vlc_lstat()

int vlc_lstat	(	const char *	filename,
		struct stat *	st )

Finds file/inode information, as lstat().

Consider using fstat() instead, if possible.

Parameters

filename	UTF-8 file path
st	the POSIX stat structure to fill

References vlc_stat(), and vlc_statEx().

vlc_rename()

int vlc_rename	(	const char *	oldpath,
		const char *	newpath )

Moves a file atomically.

This only works within a single file system.

Parameters

oldpath	path to the file before the move
newpath	intended path to the file after the move

Returns

A 0 return value indicates success. A -1 return value indicates an error, and an error code is stored in errno

vlc_stat()

int vlc_stat	(	const char *	filename,
		struct stat *	st )

Finds file/inode information - like stat().

Note

As far as possible, fstat() should be used instead.

Parameters

filename	UTF-8 file path
st	the POSIX stat structure to fill

vlc_unlink()

int vlc_unlink

(

const char *

filename

)

Removes a file.

Parameters

filename

a UTF-8 string with the name of the file you want to delete.

Returns

A 0 return value indicates success. A -1 return value indicates an error, and an error code is stored in errno
