NAME

perror - explain error codes

SYNOPSIS

TagDescription
perror [options] errorcode ...

DESCRIPTION

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 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
OS error code  13:  Permission denied
OS error code  64:  Machine is not on the network

To obtain the error message for a MySQL Cluster error code, invoke perror with the --ndb option:

shell> perror --ndb errorcode

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.
