DESCRIPTION    [Toc]    [Back]

     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    [Toc]    [Back]

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

(``POSIX'').
