'errmsg.h' and 'mysqld_error.h' files only have the definitions of the error codes. In the MySQL documentation you can find the definition along with the message it displays, which could be more useful since the error constant name isn't always explicit enough.

As of 5.5.9, connect_errno will not show an error if the host or the user (or both) are empty strings, so such cases have to be accounted for separately.
