Function Documentation

ruPtrComp()

RUAPI int32_t ruPtrComp	(	trans_ptr	testVal,
		trans_ptr	existingVal
	)

Pointer size integer comparator function for the ruType system.

Parameters

testVal	Value to compare against existing value.
existingVal	The existing value to compare testVal to.

Returns

-1 if testVal is less existingVal, 1 if testVal is greater existingVal or 0 in case both of them are equal.

ruPtrHash()

RUAPI ru_uint ruPtrHash

(

trans_ptr

key

)

Returns a hash for given pointer size integer number.

Parameters

key	Number to hash

Returns

The hash of the given number.

ruPtrMatch()

RUAPI bool ruPtrMatch	(	trans_ptr	s1,
		trans_ptr	s2
	)

Convenience pointer size integer match function for Maps.

Parameters

s1	First comparison int.
s2	Second comparison int.

Returns

true if they are equal

ruTypeIntPtr()

RUAPI ruType ruTypeIntPtr

(

void

)

Returns an ruType used for pointer size integers. Example:

// error checking left out for brevity
const char* k1 = "my key";
ruSet rs = ruSetNew(ruTypeIntPtr());
ruSetPut(rs, k1);
 
if (ruSetHas(rs, k1, NULL)) {
    printf("address: 0x%p is in the set\n", k1);
}
ruSetFree(rs);

Returns

Pointer size integer type specification. Caller need not free.
