Question

Is there a way in C to parse a piece of text and obtain values for argv and argc, as if the text had been passed to an application on the command line?

I ended up writing a function to do this myself, I don't think its very good but it works for my purposes - feel free to suggest improvements for anyone else who needs this in the future:

void parseCommandLine(char* cmdLineTxt, char*** argv, int* argc){
    int count = 1;

    char *cmdLineCopy = strdupa(cmdLineTxt);
    char* match = strtok(cmdLineCopy, " ");
 // First, count the number of arguments
    while(match != NULL){
        count++;
        match = strtok(NULL, " ");
    }

    *argv = malloc(sizeof(char*) * (count+1));
    (*argv)[count] = 0;
    **argv = strdup("test"); // The program name would normally go in here

    if (count > 1){
        int i=1;
        cmdLineCopy = strdupa(cmdLineTxt);
        match = strtok(cmdLineCopy, " ");
        do{
            (*argv)[i++] = strdup(match);
            match = strtok(NULL, " ");
        } while(match != NULL);
     }

    *argc = count;
}
