Function Documentation

InitMatcherRatings()

void InitMatcherRatings

(

register FLOAT32 *

Rating

)

MakeTempProtoPerm()

int MakeTempProtoPerm	(	void *	item1,
		void *	item2
	)

This routine converts TempProto to be permanent if its proto id is used by the configuration specified in ProtoKey.

Parameters

item1	(TEMP_PROTO) temporary proto to compare to key
item2	(PROTO_KEY) defines which protos to make permanent

Globals: none

Returns

TRUE if TempProto is converted, FALSE otherwise

Note

Exceptions: none
