I've ended up with a small collection of libraries I like to use with awk, but this means I can't do awk -f librarycode.awk '{ program code }' filename because awk will assume that anything after -f is a filename, not code. Is there any way I can do both? (6 Replies)

assert_perror
ASSERT_PERROR(3) Linux Programmer's Manual ASSERT_PERROR(3)
NAME
assert_perror - test errnum and abort
SYNOPSIS
#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <assert.h>
void assert_perror(int errnum);
DESCRIPTION
If the macro NDEBUG was defined at the moment <assert.h> was last included, the macro assert_perror() generates no code, and hence does
nothing at all. Otherwise, the macro assert_perror() prints an error message to standard error and terminates the program by calling
abort(3) if errnum is nonzero. The message contains the filename, function name and line number of the macro call, and the output of str-
error(errnum).
RETURN VALUE
No value is returned.
CONFORMING TO
This is a GNU extension.
BUGS
The purpose of the assert macros is to help the programmer find bugs in his program, things that cannot happen unless there was a coding
mistake. However, with system or library calls the situation is rather different, and error returns can happen, and will happen, and
should be tested for. Not by an assert, where the test goes away when NDEBUG is defined, but by proper error handling code. Never use
this macro.
