.PP
|
|
For most system errors, MariaDB displays, in addition to an internal text message, the system error code in one of the following styles:
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|
|
.\}
|
|
.nf
|
|
message \&.\&.\&. (errno: #)
|
|
message \&.\&.\&. (Errcode: #)
|
|
.fi
|
|
.if n \{\
|
|
.RE
|
|
.\}
|
|
.PP
|
|
You can find out what the error code means by examining the documentation for your system or by using the
|
|
\fBperror\fR
|
|
utility\&.
|
|
.PP
|
|
\fBperror\fR
|
|
prints a description for a system error code or for a storage engine (table handler) error code\&.
|
|
.PP
|
|
