Method Stdio.File()->is_open()

Method is_open

int is_open()

Description

Returns true if the file is open.

Note

If the file is a socket that has been closed from the remote side, this function might still return true.

Note

Most methods can't be called for a file descriptor that isn't open. Notable exceptions errno , mode , and the set and query functions for callbacks and backend.
