can ASM generate random numbers?

[supercoollee]

i mean, without writing a function by oneself .

Not unless you are using a VIA CPU. http://www.via.com.tw/en/initiatives/padlock/hardware.jsp#rng

No.

MASM32 includes a procedure to generate random numbers called nrand.  There is also crt_rand from msvcrt.lib.  nrand would probably be faster if that's a consideration.

With a macro you can get the assembler to generate random numbers at assembly time. There are two examples here:

not the best, but easy to implement:

Code Select Expand

rdtsc
and eax,0ffh ; 0...255

Or you can use another library... I would recommend Agner Fog's.

If you download the zip file of binary libraries, in that is another zip file with the source code (in asm).
