mexErrMsgIdAndTxt (External Interfaces Reference)

Issue error message with identifier and return to MATLAB prompt

C Syntax

#include "mex.h"
void mexErrMsgIdAndTxt(const char *identifier, 
const char *error_msg, ...);

Arguments

identifier
String containing a MATLAB message identifier. See Message Identifiers in the MATLAB documentation for information on this topic.

error_msg
String containing the error message to be displayed. The string may include formatting conversion characters, such as those used with the ANSI C sprintf function.

...
Any additional arguments needed to translate formatting conversion characters used in error_msg. Each conversion character in error_msg is converted to one of these values.

Description

Call mexErrMsgIdAndTxt to write an error message and its corresponding identifier to the MATLAB window. After the error message prints, MATLAB terminates the MEX-file and returns control to the MATLAB prompt.

Calling mexErrMsgIdAndTxt does not clear the MEX-file from memory. Consequently, mexErrMsgIdAndTxt does not invoke the function registered through mexAtExit.

If your application called mxCalloc or one of the mxCreate routines to allocate memory, mexErrMsgIdAndTxt automatically frees the allocated memory.

Note If you get warnings when using mexErrMsgIdAndTxt, you may have a memory management compatibility problem. For more information, see Memory Management Compatibility Issues in the External Interfaces documentation.
