C - Pass Variable Arguments to fprintf

http://stackoverflow.com/questions/1056411/how-to-pass-variable-number-of-arguments-to-printf-sprintf

void Error(const char* format, ...)
{
    va_list argptr;
    va_start(argptr, format);
    vfprintf(stderr, format, argptr);
    va_end(argptr);
}
If you want to manipulate the string before you display it and really do need it stored in a buffer first, please please please use vsnprintf instead of vsprintf. vsnprintf will prevent an accidental buffer overflow error.
