NAME

       explain_execvp_or_die - execute a file and report errors

SYNOPSIS

       #include <libexplain/execvp.h>
       void explain_execvp_or_die(const char *pathname, char *const *argv);

DESCRIPTION

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

       This function is intended to be used in a fashion similar to the following example:
	      explain_execvp_or_die(pathname, argv);

       pathname
	       The pathname, exactly as to be passed to the execvp(3) system call.

       argv    The argv, exactly as to be passed to the execvp(3) system call.

       Returns:
	       This function only returns on success.  On failure, prints an explanation and exits.

SEE ALSO

       execvp(3)
	       execute a file

       explain_execvp(3)
	       explain execvp(3) errors
