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();
