Module Wrappers.Unix_fd_list
type t = [ `unix_fd_list | `object_ ] Gobject.objval new_ : unit -> tCreate a new UnixFDList
val new_from_array : int array -> int -> tCreate a new UnixFDList
val steal_fds : t -> int array * intReturns the array of file descriptors that is contained in this object.
After this call, the descriptors are no longer contained in @list. Further calls will return an empty list (unless more descriptors have been added).
The return result of this function must be freed with g_free(). The caller is also responsible for closing all of the file descriptors. The file descriptors in the array are set to close-on-exec.
If @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 @list, an empty array is returned.
val peek_fds : t -> int array * intReturns the array of file descriptors that is contained in this object.
After this call, the descriptors remain the property of @list. The caller must not close them and must not free the array. The array is valid only until @list is changed in any way.
If @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 @list, an empty array is returned.
val get_length : t -> intGets the length of @list (ie: the number of file descriptors contained within).
Gets a file descriptor out of @list.
@index_ specifies the index of the file descriptor to get. It is a programmer error for @index_ to be out of range; see g_unix_fd_list_get_length().
The file descriptor is duplicated using dup() and set as close-on-exec before being returned. You must call close() on it when you are done.
A possible cause of failure is exceeding the per-process or system-wide file descriptor limit.
Adds a file descriptor to @list.
The file descriptor is duplicated using dup(). You keep your copy of the descriptor and the copy contained in @list will be closed when @list is finalized.
A possible cause of failure is exceeding the per-process or system-wide file descriptor limit.
The index of the file descriptor in the list is returned. If you use this index with g_unix_fd_list_get() then you will receive back a duplicated copy of the same file descriptor.
