mexErrMsgTxt (External Interfaces Reference)

Issue error message and return to MATLAB prompt

C Syntax

#include "mex.h"
void mexErrMsgTxt(const char *error_msg);

Arguments

error_msg
String containing the error message to be displayed.

Description

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

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

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

Note If you get warnings when using mexErrMsgTxt, you may have a memory management compatibility problem. For more information, see Memory Management Compatibility Issues.
