Write to registry to start with Windows

#include <windows.h>
#include <stdio.h>

int runWithWin(char *dsVal) {
    long ret;
    HKEY hKey;
    ret = RegCreateKey (HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Run", &hKey);
    ret = RegSetValueEx (hKey, "My Application", 0, REG_SZ, dsVal, strlen(dsVal));
    RegCloseKey (hKey);
    return 0;
}

int main(int argn, char *argv[]) {
    char mp[255];
    sprintf(mp, "\"%s\"", argv[0]);
    runWithWin(mp);
    // do something
