Hi.
a piece of my code
mlfFoo(1, &y_ptr,&error_msg, data);
y =3D mxGetPr(y_ptr);
buflen =3D mxGetM(error_msg)*sizeof(mxChar)+1; //LINE ERROR
buf =3D (char*)mxMalloc(buflen);
/* Copy the string data into buf. */
status =3D mxGetString(error_msg, buf, buflen);
It displays the following in LINE ERROR:
"Unhandled exception at 0x7ad61df7 in test.exe: 0xC0000005: Access
violation reading location 0xcccccce4."
Thanks a lot
