                                                                                         explain_execv_or_die(3)

       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.

       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);

       explain_execv_or_die - execute a file and report errors

       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.

execv(3)
               execute a file

       explain_execv(3)
               explain execv(3) errors

       exit(2) terminate the calling process

       #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);
