MirOS Manual: getpid(2), getppid(2)

GETPID(2)                  BSD Programmer's Manual                   GETPID(2)

NAME

     getpid, getppid - get parent or calling process identification

SYNOPSIS

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

     pid_t
     getpid(void);

     pid_t
     getppid(void);

DESCRIPTION

     getpid() returns the process ID of the calling process. Though the ID is
     guaranteed to be unique, it should NOT be used for constructing temporary
     file names; see mkstemp(3) instead.

     getppid() returns the process ID of the parent of the calling process.

ERRORS

     The getpid() and getppid() functions are always successful, and no return
     value is reserved to indicate an error.

STANDARDS

     getpid() and getppid() conform to IEEE Std 1003.1-1988 ("POSIX").
