Function Documentation

ruBoolComp()

RUAPI int32_t ruBoolComp	(	trans_ptr	testVal,
		trans_ptr	existingVal
	)

boolean 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.

ruBoolHash()

RUAPI ru_uint ruBoolHash

(

trans_ptr

key

)

Returns a hash for given boolean number.

This is nonsense for a map but is here since types are used as values as well.

Parameters

key	boolean to hash

Returns

The hash of the given boolean i.e 1 or 0.

ruBoolMatch()

RUAPI bool ruBoolMatch	(	trans_ptr	testKey,
		trans_ptr	existingKey
	)

Convenience boolean match function for Maps.

Parameters

testKey	First comparison bool.
existingKey	Second comparison bool.

Returns

true if they are equal

ruBoolRefPtr()

RUAPI ptr ruBoolRefPtr

(

ptr

in

)

Returns the content of the given boolean address as pointer.

Parameters

in	address to a boolean

Returns

content of given address in pointer sized field

ruRefPtrBool()

RUAPI int32_t ruRefPtrBool	(	ptr	src,
		ptr *	dst
	)

Copies the boolean stored in src to dst.

Parameters

src	Where the boolean is stored, usually in the collection.
dst	Where the value will be copied to properly type casted.

Returns

RUE_OK unless dst is not set.

ruTypeBool()

RUAPI ruType ruTypeBool

(

void

)

Returns an ruType used for booleans.

Returns

boolean type specification. Caller need not free.
