NAME

       explain_waitpid_or_die  -  wait  for process to change state and report
       errors

SYNOPSIS

       #include <libexplain/waitpid.h>
       int pid = explain_waitpid_or_die(int pid, int *status, int options);

DESCRIPTION

       The explain_waitpid_or_die function is  used  to  call  the  waitpid(2)
       system  call.   On  failure  an  explanation will be printed to stderr,
       obtained from explain_waitpid(3), and then the  process  terminates  by
       calling exit(EXIT_FAILURE).

       This  function  is  intended  to  be  used  in a fashion similar to the
       following example:
              explain_waitpid_or_die(pid, status, options);

       pid     The pid, exactly as to be passed to the waitpid(2) system call.

       status  The  status,  exactly  as to be passed to the waitpid(2) system
               call.

       options The options, exactly as to be passed to the  waitpid(2)  system
               call.

       Returns:
               This  function  only returns on success.  On failure, prints an
               explanation and exits.
