NAME
ttyslot() - find the slot in the utmp file of the current user
SYNOPSIS
#include <stdlib.h>
int ttyslot(void);
DESCRIPTION
ttyslot() returns the index of the current user’s entry in the /etc/utmp file. This is accomplished
by scanning /etc/utmp for the name of the terminal associated with the standard input, standard out-
put, or standard error (file descriptor 0, 1 or 2).
RETURN VALUE
ttyslot() returns −1 if an error was encountered while searching for the terminal name or if none of
file descriptors 0, 1, or 2 is associated with a terminal device.
APPLICATION USAGE
ttyslot() is thread-safe. It is not async-cancel-safe. A cancellation point may occur when a thread is
executing ttyslot().
WARNINGS
Obsolescent Interfaces
ttyslot() is to be obsoleted at a future date.
FILES
/etc/utmp
