7.12 perror , Explaining Error Codes

For most system errors, MySQL displays, in addition to an internal text message, the system error code in one of the following styles:

message ... (errno: #) message ... (Errcode: #)

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

perror prints a description for a system error code or for a storage engine (table handler) error code.

Invoke perror like this:

shell> perror [ options ] errorcode ...

Example:

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

Note that the meaning of system error messages may be dependent on your operating system. A given error code may mean different things on different operating systems.
