Minor change in StrMidA

[HSE]

Hi Biterider!

I have some problems extracting only 1 byte string. With a minor change apparently is working well:

Code Select Expand

    invoke StrLengthA, [esp + 8]
; Agregated         
    inc eax     ; 27/09/16
    mov ecx, eax
; Replaced
    ;inc ecx     ; 27/09/16


Regards

LATER: not solved at all. But MASM32 szMid make the job until I understand the function (forever?  )

Hi HSE
Sorry for the delay, but I was a bit busy. I found a problem when the starting character was the last in the source string. Due to a wrang comparison, the function was aborted returning zero.
Attached the corrected version of the ANSI and the wide string functions. BTW, when the function returns, eax contains the number of chars copied.

Code Select Expand

m2z BYTE ptr [edx]                                  ;Set ZTC

Can you explain what this line does? Just curious.

Code Select Expand

mov byte ptr [edx], 0

If function fail return a null string.
