The file descriptor is duplicated using dup(). You keep your copy

when @list is finalized.
A possible cause of failure is exceeding the per-process or

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.
