mexWarnMsgIdAndTxt (C and Fortran)

Warning message with identifier

C Syntax

#include "mex.h"
void mexWarnMsgIdAndTxt(const char *warningid,
  const char *warningmsg, ...);

Fortran Syntax

#include "fintrf.h"
subroutine mexWarnMsgIdAndTxt(warningid, warningmsg)
character*(*) warningid, warningmsg



String containing a MATLAB® message identifier. For information on creating identifiers, see Message Identifiers.


String to display. In C, the string can include conversion specifications, used by the ANSI® C printf function.


In C, any arguments used in the message. Each argument must have a corresponding conversion specification. Refer to your C documentation for printf conversion tables.


The mexWarnMsgIdAndTxt function writes a warning message to the MATLAB command prompt. The warnings displayed are the same as warnings issued by the MATLAB warning function. To control the information displayed or suppressed, call the warning function with the desired settings before calling your MEX-file.

Unlike mexErrMsgIdAndTxt, calling mexWarnMsgIdAndTxt does not terminate the MEX-file.
