GETPGRP(3P)               POSIX Programmer's Manual              GETPGRP(3P)
       This manual page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior), or
       the interface may not be implemented on Linux.
       getpgrp — get the process group ID of the calling process
       #include <unistd.h>
       pid_t getpgrp(void);
       The getpgrp() function shall return the process group ID of the
       calling process.
       The getpgrp() function shall always be successful and no return value
       is reserved to indicate an error.
       No errors are defined.
       The following sections are informative.
       None.

       4.3 BSD provides a getpgrp() function that returns the process group
       ID for a specified process. Although this function supports job
       control, all known job control shells always specify the calling
       process with this function. Thus, the simpler System V getpgrp()
       suffices, and the added complexity of the 4.3 BSD getpgrp() is
       provided by the XSI extension getpgid().
