Function Documentation

ruLongComp()

RUAPI int32_t ruLongComp	(	trans_ptr	testVal,
		trans_ptr	existingVal
	)

long 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.

ruLongHash()

RUAPI ru_uint ruLongHash

(

trans_ptr

key

)

Returns a hash for given long integer number.

Parameters

key	Number to hash

Returns

The hash of the given number.

ruLongMatch()

RUAPI bool ruLongMatch	(	trans_ptr	s1,
		trans_ptr	s2
	)

Convenience long integer match function for Maps.

Parameters

s1	First comparison int.
s2	Second comparison int.

Returns

true if they are equal

ruLongRefPtr()

RUAPI ptr ruLongRefPtr

(

ptr

in

)

Returns the content of the given long integer address as pointer.

Parameters

in	address to long integer

Returns

content of given address in pointer sized field

ruRefPtrLong()

RUAPI int32_t ruRefPtrLong	(	ptr	src,
		ptr *	dst
	)

Copies the long integer stored in src to dst.

Parameters

src	Where the long integer 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.

ruTypeLong()

RUAPI ruType ruTypeLong

(

void

)

Returns an ruType used for long integers. Example:

// error checking left out for brevity
long k1 = 23, v1 = 42, r = 0;
ruMap rm = ruMapNew(ruTypeLong(), ruTypeLong());
ruMapPut(rm, &k1, &v1);
 
ruMapGet(rm, &k1, &r);
printf("k: %ld v: %ld\n", k1, r);
ruMapFree(rm);

Returns

long integer type specification. Caller need not free.
