explain_stime_or_die(3) Library Functions Manual explain_stime_or_die(3)NAME
explain_stime_or_die - set system time and report errors
SYNOPSIS
#include <libexplain/stime.h>
void explain_stime_or_die(time_t *t);
int explain_stime_on_error(time_t *t);
DESCRIPTION
The explain_stime_or_die function is used to call the stime(2) system call. On failure an explanation will be printed to stderr, obtained
from the explain_stime(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_stime_on_error function is used to call the stime(2) system call. On failure an explanation will be printed to stderr, obtained
from the explain_stime(3) function, but still returns to the caller.
t The t, exactly as to be passed to the stime(2) system call.
RETURN VALUE
The explain_stime_or_die function only returns on success, see stime(2) for more information. On failure, prints an explanation and exits,
it does not return.
The explain_stime_on_error function always returns the value return by the wrapped stime(2) system call.
EXAMPLE
The explain_stime_or_die function is intended to be used in a fashion similar to the following example:
explain_stime_or_die(t);
SEE ALSO stime(2)
set system time
explain_stime(3)
explain stime(2) errors
exit(2) terminate the calling process

explain_getpgrp_or_die - get process group and report errors
SYNOPSIS
#include <libexplain/getpgrp.h>
pid_t explain_getpgrp_or_die(pid_t pid);
pid_t explain_getpgrp_on_error(pid_t pid);
DESCRIPTION
The explain_getpgrp_or_die function is used to call the getpgrp(2) system call. On failure an explanation will be printed to stderr,
obtained from the explain_getpgrp(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_getpgrp_on_error function is used to call the getpgrp(2) system call. On failure an explanation will be printed to stderr,
obtained from the explain_getpgrp(3) function, but still returns to the caller.
pid The pid, exactly as to be passed to the getpgrp(2) system call.
API Inconsistencies
Note: the getpgrp(2) function has two implementations. The POSIX.1 version has no arguments, while the BSD version has one argument. For
simplicity of implementation, the argument list seen here includes the pid argument.
The POSIX.1 getpgid() semanatics can be obtained by calling getpgrp(0) on BSD systems, and this is the API for libexplain, even on systems
that do not use the BSD API.
RETURN VALUE
The explain_getpgrp_or_die function only returns on success, see getpgrp(2) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_getpgrp_on_error function always returns the value return by the wrapped getpgrp(2) system call.
EXAMPLE
The explain_getpgrp_or_die function is intended to be used in a fashion similar to the following example:
pid_t result = explain_getpgrp_or_die(pid);
SEE ALSO getpgrp(2)
get process group
explain_getpgrp(3)
explain getpgrp(2) errors
exit(2) terminate the calling process

I run this command from the script on SUN
ps -p $PID -o pid,ppid,pcpu,pmem,user,stime,etime,args
Now need to move my script on HP.
It should be possible construct similar on HP ... but I can't figure it out. ps on HP does not -o formatting option
