Here's mine.  The exact formatting is NOT IMPORTANT.  What DOES matter
is the comments and the fact that it is obvious how one gets each
possible return value.

	#include	<stdio.h>

	#define	MAGIC	'\0'	/* silly terminating character value */

	int			/* returns EOF or MAGIC (why??) */
	some_function( void )	/* ANSI C assumed; else delete "void" */
		{
		int	c;	/* character from standard input */

		while ( (c = getchar()) != EOF )
			if ( c == MAGIC )
				return MAGIC;

		return EOF;
		}
