◆ IM2_last_error_message()

M2_string IM2_last_error_message ( void )

Engine error handling mechanism. Any engine routine which encounters an error (e.g. Rings not the same) often returns a NULL value, and sets an error message, which can be obtained from this routine. Any routine that can set this may return a type such as "MatrixOrNull". This routine clears the error message and returns it.
