variableNXPtrPrototype

The two following prototypes are useful for manipulating set of pointers or set of strings; For them free is defined as NXNoEffectFree
OBJC_EXPORT const NXHashTablePrototype NXPtrPrototype

variableNXStrPrototype

OBJC_EXPORT const NXHashTablePrototype NXStrPrototype

variableNXPtrStructKeyPrototype

following prototypes help describe mappings where the key is the first element of a struct and is either a pointer or a string. For example NXStrStructKeyPrototype can be used to hash pointers to Example, where Example is: typedef struct { char *key; int data1; ... } Example For the following prototypes, free is defined as NXReallyFree.
