| + | ====== The error codes of $sockerr ====== | ||
| + | //Author// --- //[[saturn@xise.nl|Saturn]] 2006/09/17 15:25// | ||
| + | Every mIRC scripter who has ever worked with sockets, knows how important it is to check $sockerr in socket events. From the /sockread example in the mIRC helpfile, we also know that it is always a positive numerical value: zero on success, above zero if an error occurred. But exactly what are the error codes that $sockerr can return? | ||
| + | |||
| + | Below is a list of $sockerr codes and possible meanings, which are different per event. This list is not necessarily complete or even fully correct. | ||
| + | |||

| + | 0: success | ||
| + | 3: failure establishing socket connection (W) | ||

| + | **on SOCKLISTEN** | ||
| + | 0: new socket successfully accepted | ||
| + | 1: error occurred on listening socket (W) (R) | ||
