	This routine will return the number of occurrences of a substring
	in a string.

	string		string to search
	length		length of string to search (a value of zero
			will result in a search up to a null terminator)
	match_string	string to be searched for
	match_length	length of string to be searched for  (If this argument
			has a value of zero, the routine will determine
			the length of the string.)
	case_sensitive	case sensitivity flag
			(TRUE -> case sensitive search,
			 FALSE -> case insensitive search)
	wildcard	wildcard character which will match any
			single character
			(STR_NO_WILDCARD -> don't use any wildcards,
			 otherwise -> desired wildcard character)
	ignore_spaces	white space handling flag
			(TRUE -> ignore embedded white spaces,
			 FALSE -> treat white spaces like any other character)

	This function returns status values as follows:

	CLIB_INVARG		invalid argument passed
	CLIB_MEMFAIL		dynamic memory allocation failure
	otherwise		number of occurrences of specified substring

	This function requires the following include files:
