DESCRIPTION

XListDepths() returns the array of depths that are available on the specified screen.  If the specified screen_number is valid and sufficient memory for the array can be allocated, XListDepths() sets count_return to the number of available depths.  Otherwise, it does not set count_return and returns NULL.  To release the memory allocated for the array of depths, use XFree().
