getppid

getpid(2)							System Calls Manual							 getpid(2)

NAME

       getpid, getpgrp, getppid - Gets the process ID, process group ID, parent process ID

SYNOPSIS

       #include <unistd.h>

       pid_t getpid( void );

       pid_t getpgrp( void );

       pid_t getppid( void );

       Application  developers	may  want  to  specify an #include statement for <sys/types.h> before the one for <unistd.h> if programs are being
       developed for multiple platforms. The additional #include statement is not required on Tru64 UNIX systems or by ISO  or	X/Open	standards,
       but may be required on other vendors' systems that conform to these standards.

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       getpid(), getpgrp(), getppid():	POSIX.1, XPG4, XPG4-UNIX

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

DESCRIPTION

       The getpid() function returns the process ID of the calling process.

       The getpgrp() function returns the process group ID of the calling process.

       The  getppid()  function  returns  the  parent  process ID of the calling process.  When a process is created, its parent process ID is the
       process ID of its parent process.  If a parent process exits, the parent process IDs of its child processes are changed to the  process	ID
       of the init program.
