NAME

       explain_execv_or_die - execute a file and report errors

SYNOPSIS

       #include <libexplain/execv.h>
       void explain_execv_or_die(const char *pathname, char *const*argv);
       int explain_execv_on_error(const char *pathname, char *const*argv);

DESCRIPTION

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

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

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

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

RETURN VALUE

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

       The explain_execv_on_error function  always  returns  the  value  return  by  the  wrapped
       execv(3) system call.

EXAMPLE

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