UnixFDList.get

int get(int index)

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 [gio.unix_fdlist.UnixFDList.getLength].

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.

Parameters

index the index into the list

Returns

the file descriptor, or -1 in case of error

Throws

[ErrorWrap]
