Breaking down WinMain's cmdLine in old style main()'s arguments

Question

I want to convert WinMain\'s cmdLine argument to argc and argv so I can use the argument parsing function I wrote for con

Answer 1

If you want plain int argc, char** argv arguments you have to do it on your own.

void fetchCmdArgs(int* argc, char*** argv) {
    // init results
    *argc = 0;

    // prepare extraction
    char* winCmd = GetCommandLine();
    int index = 0;
    bool newOption = true;
    // use static so converted command line can be
    // accessed from outside this function
    static vector argVector;

    // walk over the command line and convert it to argv
    while(winCmd[index] != 0){
        if (winCmd[index] == ' ') {
            // terminate option string
            winCmd[index] = 0;
            newOption = true;

        } else  {
            if(newOption){
                argVector.push_back(&winCmd[index]);
                (*argc)++;  
            }
            newOption = false;
        }
        index++;
    }

    // elements inside the vector are guaranteed to be continous
    *argv = &argVector[0];
}


// usage
int APIENTRY WinMain(...) {
    int argc = 0;
    char** argv;
    fetchCmdArgs(&argc, &argv);
}
