explain_tmpfile_or_die(3) Library Functions Manual explain_tmpfile_or_die(3)NAME
explain_tmpfile_or_die - create a temporary file and report errors
SYNOPSIS
#include <libexplain/tmpfile.h>
FILE *explain_tmpfile_or_die(void);
FILE *explain_tmpfile_on_error(void);
DESCRIPTION
The explain_tmpfile_or_die function is used to call the tmpfile(3) system call. On failure an explanation will be printed to stderr,
obtained from the explain_tmpfile(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_tmpfile_on_error function is used to call the tmpfile(3) system call. On failure an explanation will be printed to stderr,
obtained from the explain_tmpfile(3) function, but still returns to the caller.
RETURN VALUE
The explain_tmpfile_or_die function only returns on success, see tmpfile(3) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_tmpfile_on_error function always returns the value return by the wrapped tmpfile(3) system call.
EXAMPLE
The explain_tmpfile_or_die function is intended to be used in a fashion similar to the following example:
FILE *result = explain_tmpfile_or_die();
SEE ALSO tmpfile(3)
create a temporary file
explain_tmpfile(3)
explain tmpfile(3) errors
exit(2) terminate the calling process

explain_getpgrp_or_die(3) Library Functions Manual explain_getpgrp_or_die(3)NAME
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

Can somebody explain me what exactly will happen with this command, step by step.
eval sed " -e 's/?1/${JOB_NAME}/g' -e 's/?DT/${DT}/g'" ${SCRIPT_1} > ${SCRIPT_1_2} 2> ${tmpfile} (1 Reply)
hi, I have two users, let us call them A and B.
I do as User A
touch tmpfile
chmod 700 tmpfile
Now as User B I do rm tmpfile - and it allows me to do it (after prompting me)...why?
If I had done chmod 777 tmpfile, then sure User B should be able to delete it, but I did chmod 700... (3 Replies)
say I want to insert "this is a test" as the first line into file A, besides
echo "this is a test" > /tmp/tmpfile
cat /tmp/tmpfile fileA >> /tmp/result,
is there any simple way I can do it? thanks (7 Replies)
Folks
Appreciate your help in understanding issue in relation to below.
I need to pul uvalue from a file (tmpfile) and compare it with a number to make decision.
Using #!/bin/sh
contents of tmpfile :
Slot uvalue : 0.16
How I am pulling it:
unifval=`awk '/uvalue/ {print $4}' tmpfile` ... (1 Reply)
We are using this function tmpfile() :
FILE *tmpfp ;
if ((tmpfp = tmpfile()) == NULL)
{
fprintf(stderr, "%s: ERROR: init_operator(): ", ROUTINE);
perror("tmpfile()");
exit(ERR_OPEN);
}
and the above is raising error :
MSMD0603: ERROR:... (3 Replies)
