On Windows and Unix, the main function can actually accept 3 parameter! Third parameter, envp, is an array of environment variables:

int main(int argc, char **argv, char **envp);

On OS X, there is a fourth argument that supplies arbitrary information from the OS (such as the program path):

int main(int argc, char **argv, char **envp, char **apple);
