NAME

       explain_vasprintf_or_die - print to allocated string and report errors

SYNOPSIS

       #include <libexplain/vasprintf.h>
       int explain_vasprintf_or_die(char **data, const char *format, va_list ap);
       int explain_vasprintf_on_error(char **data, const char *format, va_list ap);

DESCRIPTION

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

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

       data    The data, exactly as to be passed to the vasprintf(3) system call.

       format  The format, exactly as to be passed to the vasprintf(3) system call.

       ap      The ap, exactly as to be passed to the vasprintf(3) system call.

RETURN VALUE

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

       The explain_vasprintf_on_error function always returns the  value  return  by  the  wrapped  vasprintf(3)
       system call.

EXAMPLE

       The  explain_vasprintf_or_die  function  is  intended  to  be  used in a fashion similar to the following
       example:
              int result = explain_vasprintf_or_die(data, format, ap);
