I need to determine the first char of a buffer by using
a pointer. So far this isnt working...
mov esi, offset bSocketBuffer
.if byte ptr != "2"
jmp Cleanup
.endif
I think I solved it with:
mov eax, bSocketBuffer
mov dl, byte ptr
.if dl != "2"
jmp Cleanup
.endif
// mov eax, bSocketBuffer
// mov dl, byte ptr
// .if dl != "2"
// jmp Cleanup
// .endif
hm, you forget calculating the offset...
but i think it's better to use this:
mov eax,offset bSocketBuffer
cmp byte ptr ,"2"
jnz Cleanup

Try this if you need to test a single byte in a buffer
mov al, buffer[0]
This is what I'm using now. Its the only thing that seems
to work right. Note that
bSocketBuffer
mov eax, bSocketBuffer
.if byte ptr != "2"
jmp Cleanup
.else
you can't say that this is not working,
it's the same but shorter & faster:
cmp byte ptr bSocketBuffer[0],"2"
jnz Cleanup
just go to iczelions site and you will
find a lot of wonderfull resources (links)
about asm basics like conditional jumps.
bye and good luck in your project.
Sorry,
With the code I using now the the app jumps to
CleanupCleanupcmp byte ptr , "2"
jnz Cleanup
try that...
a better name for bSocketBuffer would be lpSocketBuffer, then it would be easier to see that it's really a pointer to a buffer and not the buffer itself. lp = long pointer
