: lasterr = lasterror ()

: lasterror (err)

: lasterror ("reset")

Query or set the last error message structure.

When called without arguments, return a structure containing the last error message and other information related to this error. The elements of the structure are:

message

The text of the last error message

identifier

The message identifier of this error message

stack

A structure containing information on where the message occurred. This may be an empty structure if the information cannot be obtained. The fields of the structure are:

file

The name of the file where the error occurred

name

The name of function in which the error occurred

line

The line number at which the error occurred

column

An optional field with the column number at which the error occurred

The last error structure may be set by passing a scalar structure, err, as input. Any fields of err that match those above are set while any unspecified fields are initialized with default values.

If lasterror is called with the argument "reset", all fields are set to their default values.
