peek_fds

Returns the array of file descriptors that is contained in this object.

After this call, the descriptors remain the property of this. The caller must not close them and must not free the array. The array is valid only until this is changed in any way.

If return.length is non-`NULL` then it is set to the number of file descriptors in the returned array. The returned array is also terminated with `-1`.

This function never returns `NULL`. In case there are no file descriptors contained in this, an empty array is returned.

Parameters:

this	a [class@Gio.UnixFDList]
length	pointer to the length of the returned array, or `NULL`

Returns:

an array of file descriptors
