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();
