This example shows how to add undefine preprocessor directives to a build information object.

Suppose you have two files, myFile.c and myInc.h, in your current working folder.

// myFile.c
#include <stdio.h>
int main(void) {
    #ifdef __STDC_VERSION__
    printf("__STDC_VERSION__ is defined\n");
    printf("__STDC_VERSION__ is not defined\n");
    #ifdef MY_MACRO
    printf("MY_MACRO is defined\n");
    printf("MY_MACRO is not defined\n");

// myInc.h
#ifndef MYINC_H
#define MYINC_H
#define MY_MACRO

Create an RTW.BuildInfo object and specify source files, undefine directives, and preinclude files.

buildInfo = RTW.BuildInfo;
buildInfo.ComponentName = 'MyComponent';
addSourceFiles(buildInfo, 'myfile.c');
addUndefines(buildInfo, '__STDC_VERSION__');
addPreincludeFiles(buildInfo, 'myinc.h', pwd);
