 Name

    ttyslot - find the slot in the utmp file of the current user

 Syntax


    cc  . . .  -lc


    #include <stdlib.h>

    int ttyslot ()


 Description

    The ttyslot function returns the index of the current user's entry in the
    /etc/utmp file.  This is accomplished by actually scanning the file
    /etc/inittab for the name of the terminal associated with the standard
    input, the standard output, or the error output (0, 1 or 2).

 Files

    /etc/inittab
    /etc/utmp

 Diagnostics

    A value of -1 is returned if an error was encountered while searching for
    the terminal name or if none of the above file descriptors is associated
    with a terminal device.
