/**
* g_access:
* @filename: a pathname in the GLib file name encoding
* @mode: as in access()
*
* A wrapper for the POSIX access() function. This function is used to
* test a pathname for one or several of read, write or execute
* permissions, or just existence. On Windows, the underlying access()
* function in the C library only checks the READONLY attribute, and
* does not look at the ACL at all. Software that needs to handle file
* permisssions on Windows more exactly should use the Win32 API.
*
* See the C library manual for more details about access().
*
* Returns: zero if the pathname refers to an existing file system
* object that has all the tested permissions, or -1 otherwise or on
* error.
*
* Since: 2.7
