vlc_DIR

typedef DIR vlc_DIR

Function Documentation

vlc_closedir()

void vlc_closedir

(

vlc_DIR *

dir

)

References vlc_DIR::entry, vlc_DIR::fHandle, and vlc_DIR::wildcard.

vlc_getcwd()

char * vlc_getcwd

(

void

)

Determines the current working directory.

Returns

the current working directory (must be free()'d) or NULL on error

References getenv(), ToLocaleDup, and unlikely.

Referenced by vlc_path2uri().

vlc_loaddir()

int vlc_loaddir	(	vlc_DIR *	dir,
		char ***	namelist,
		int(*)(const char *)	select,
		int(*)(const char **, const char **)	compar
	)

Does the same as vlc_scandir(), but takes an open directory pointer instead of a directory path.

References compar, compar_void(), dummy_select(), likely, strdup(), unlikely, vlc_qsort(), vlc_readdir(), and vlc_rewinddir().

Referenced by vlc_scandir().

vlc_mkdir()

int vlc_mkdir	(	const char *	dirname,
		mode_t	mode
	)

Creates a directory.

Parameters

dirname	a UTF-8 string with the name of the directory that you want to create.
mode	directory permissions

Returns

0 on success, -1 on error (see errno).

References ToLocaleDup, unlikely, and widen_path().

Referenced by ArtCacheCreateDir(), config_CreateDir(), config_GetHomeDir(), and GetTmpFile().

vlc_opendir()

vlc_DIR * vlc_opendir

(

const char *

dirname

)

Opens a DIR pointer.

Parameters

dirname

UTF-8 representation of the directory name

Returns

a pointer to the DIR struct, or NULL in case of error. Release with vlc_closedir().

References vlc_DIR::drives, vlc_DIR::entry, vlc_DIR::eol, vlc_DIR::fHandle, vlc_DIR::insert_dot_dot, strdup(), ToLocaleDup, vlc_DIR::u, unlikely, vlc_DIR::wdir, and vlc_DIR::wildcard.

Referenced by input_FindArtInCache(), subtitles_Detect(), and vlc_scandir().

vlc_readdir()

const char * vlc_readdir

(

vlc_DIR *

dir

)

Reads the next file name from an open directory.

Parameters

dir	directory handle as returned by vlc_opendir() (must not be used by another thread concurrently)

Returns

a UTF-8 string of the directory entry. The string is valid until the next call to vlc_readdir() or vlc_closedir() on the handle. If there are no more entries in the directory, NULL is returned. If an error occurs, errno is set and NULL is returned.

References vlc_DIR::drives, vlc_DIR::entry, vlc_DIR::eol, vlc_DIR::fHandle, vlc_DIR::insert_dot_dot, strdup(), vlc_DIR::u, and vlc_DIR::wdir.

vlc_rewinddir()

void vlc_rewinddir

(

vlc_DIR *

dir

)

References vlc_DIR::drives, vlc_DIR::fHandle, vlc_DIR::u, vlc_DIR::wdir, and vlc_DIR::wildcard.

vlc_scandir()

int vlc_scandir	(	const char *	dirname,
		char ***	namelist,
		int(*)(const char *)	select,
		int(*)(const char **, const char **)	compar
	)

Selects file entries from a directory, as GNU C scandir().

Parameters

dirname	UTF-8 directory path
pointer	[OUT] pointer set, on successful completion, to the address of a table of UTF-8 filenames. All filenames must be freed with free(). The table itself must be freed with free() as well.

Returns

How many file names were selected (possibly 0), or -1 in case of error.
