 getpid(2)                                                         getpid(2)





 NAME
      getpid, getpgrp, getppid, getpgrp2 - get process, process group, and
      parent process ID

 SYNOPSIS
      #include <unistd.h>

      pid_t getpid(void);

      pid_t getpgrp(void);

      pid_t getppid(void);

      pid_t getpgrp2(pid_t pid);

 DESCRIPTION
      The following functions return the information indicated:

           getpid()          Process ID of the calling process.

           getpgrp()         Process group ID of the calling process.

           getppid()         Parent process ID of the calling process.

           getpgrp2()        Process group ID of the specified process.  If
                             pid is zero, the call applies to the current
                             process.  For this to be allowed, the current
                             process and the referenced process must be in
                             the same session.

 ERRORS
      getpgrp2 fails if any of the following conditions are encountered:

           [EPERM]        The current process and the specified process are
                          not in the same session.

           [ESRCH]        No process can be found corresponding to that
                          specified by pid.
