GETPID(2) DragonFly System Calls Manual GETPID(2)
NAME
 getpid, getppid -- get parent or calling process identification
LIBRARY
 Standard C Library (libc, -lc)
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, for security reasons; 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.
SEE ALSO
 lwp_gettid(2), gethostid(3)
STANDARDS
 The getpid() and getppid() function calls are expected to conform to
 ISO/IEC 9945-1:1990 (``POSIX.1'').
HISTORY
 A getpid() function call appeared in Version 7 AT&T UNIX.
