If a user function needs to print output, it must use one of the following functions. The normal C functions that print to stdout such as printf(), puts(), etc. must not be used, as they will interfere with normal output and will not be redirected to <EXEC> or <CAPTURE> as needed. These functions do not automatically HTML-escape their output; the %H format code must explicitly be used with VXpf() for escapement.

  • VXpf(const char *fmt, ...) Replacement for printf(); has the same syntax. Also understands the same extended codes that <fmt> does.

  • VXwrite(const char *buf, size_t len) Prints len bytes of buf to the current output. Binary data is permitted.
