- * sprintf_irc
- *
- * sprintf_irc is optimized for the formats: %c, %s, %lu, %d and %u.
- * Where %lu actually equals %l09u (for printing time_t timestamps).
- *
- * sprintf_irc is NOT optimized for any other format and resorts to using
- * the normal sprintf when it encounters a format it doesn't understand
- * (including padding, width, precision etc).
- *
- * The following benchmark was measured on a PPro200 with linux 2.0.30,
- * libc 5.4.28, compiled with gcc-2.7.2.1 with -O3.
- *
- * Format sprintf sprintf_irc Speed up factor
- *
- * "12345678901234567890" 3.385 us 0.859 us 3.94

- * "%c%c%c", c1, c2, c3 3.640 us 0.376 us 9.68
