Hello there,
I've called countless C function in dll's and got a long or ulong
return value, but now i need to get a longlong value returned.
Any way to do this in Euphoria?
Here's the C function:
---------------------------------------------------------------------------------
LONGLONG Int32x32To64(
LONG Multiplier, // 1st signed 32-bit integer for the multiplication
LONG Multiplicand // 2nd signed 32-bit integer for the multiplication
);
Please note that the function's return value is a 64-bit value,
not a LARGE_INTEGER structure.
---------------------------------------------------------------------------------
This function takes two 32 bit numbers and multiplies them, then returns
the 64 bit value as a 'value', not as a structure of two 32 bit values
(ie not a pointer).
If not in raw Euphoria, then perhaps some suggestions for some
machine code? (Intel based please)
The machine code would have to access this function (link to it,
NOT do the multiplication itself), and NOT in a dll where the C func
can be called and return value poked into memory. Thanks.
Take care,
Al
And, good luck with your Euphoria programming!

Al:
How about defining the return as a C_DOUBLE which is 8 bytes ?

Hello Bernie,
I'll try it, and it sounds good to me as i can then use the atom
convert to sequence function to convert to 8 bytes.
Thanks for the idea.
