One way is to use the oft-overlooked third argument to main:

	int main(int argc, char **argv, char **env)
	{
		return 0;	/* ...or whatever... */
	}

env is an array containing all the environment variables.  I recently
posted a little utility called `printenv' which uses this to display any
or all environment variables' values.
