NAME

explain_execlp_or_die - execute a file and report errors  

SYNOPSIS

#include <libexplain/execlp.h>

void explain_execlp_or_die(, ...);
int explain_execlp_on_error(, ...);  

DESCRIPTION

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

The explain_execlp_on_error function is used to call the execlp(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_execlp(3) function, but still returns to the caller.  

RETURN VALUE

The explain_execlp_or_die function only returns on success, see execlp(3) for more information. On failure, prints an explanation and exits, it does not return.

The explain_execlp_on_error function always returns the value return by the wrapped execlp(3) system call.  

EXAMPLE

The explain_execlp_or_die function is intended to be used in a fashion similar to the following example:
explain_execlp_or_die();
