8.13 perror, Explaining Error Codes

For most system errors MySQL will, in addition to a internal text message, also print the system error code in one of the following styles: message ... (errno: #) or message ... (Errcode: #).

You can find out what the error code means by either examining the documentation for your system or use the perror utility.

perror prints a description for a system error code, or an MyISAM/ISAM storage engine (table handler) error code.

perror is invoked like this:

 
shell> perror [OPTIONS] [ERRORCODE [ERRORCODE...]]

Example:

shell> perror 13 64
Error code  13:  Permission denied
Error code  64:  Machine is not on the network

Note that the error messages are mostly system dependent!
