-FUNCTION
-	<<strchr>>---search for character in string
-
-INDEX
-	strchr
-
-ANSI_SYNOPSIS
-	#include <string.h>
-	char * strchr(const char *<[string]>, int <[c]>);
-
-TRAD_SYNOPSIS
-	#include <string.h>
-	char * strchr(<[string]>, <[c]>);
-	const char *<[string]>;
-	int <[c]>;
-
-DESCRIPTION
-	This function finds the first occurence of <[c]> (converted to
-	a char) in the string pointed to by <[string]> (including the
-	terminating null character).
-
-RETURNS
-	Returns a pointer to the located character, or a null pointer
-	if <[c]> does not occur in <[string]>.
-
-PORTABILITY
-<<strchr>> is ANSI C.
-
-<<strchr>> requires no supporting OS subroutines.
-
-QUICKREF
-	strchr ansi pure
