tcgetpgrp(3c)

Standard C Library Functions                                     tcgetpgrp(3C)



NAME
       tcgetpgrp - get foreground process group ID

SYNOPSIS
       #include <sys/types.h>
       #include <unistd.h>

       pid_t tcgetpgrp(int fildes);

DESCRIPTION
       The  tcgetpgrp() function will return the value of the process group ID
       of the foreground process group associated with the terminal.


       If there is no foreground process group, tcgetpgrp()  returns  a  value
       greater than 1 that does not match the process group ID of any existing
       process group.


       The tcgetpgrp() function is allowed from a process that is a member  of
       a  background  process  group;  however,  the information may be subse‐
       quently changed by a process that is a member of a  foreground  process
       group.

RETURN VALUES
       Upon  successful  completion,  tcgetpgrp()  returns  the  value  of the
       process group ID of the foreground process associated with  the  termi‐
       nal. Otherwise, −1 is returned and errno is set to indicate the error.

ERRORS
       The tcgetpgrp() function will fail if:

       EBADF     The fildes argument is not a valid file descriptor.


       ENOTTY    The  calling process does not have a controlling terminal, or
                 the file is not the controlling terminal.
