Function

GLibcanonicalize_filename

since: 2.58

Declaration [src]

gchar*
g_canonicalize_filename (
  const gchar* filename,
  const gchar* relative_to
)

Description [src]

Gets the canonical file name from filename. All triple slashes are turned into single slashes, and all .. and .s resolved against relative_to.

Symlinks are not followed, and the returned path is guaranteed to be absolute.

If filename is an absolute path, relative_to is ignored. Otherwise, relative_to will be prepended to filename to make it absolute. relative_to must be an absolute path, or NULL. If relative_to is NULL, it’ll fallback to g_get_current_dir().

This function never fails, and will canonicalize file paths even if they don’t exist.

No file system I/O is done.

Available since: 2.58
