szlength()

[Neo_Reloaded]

By Ksbunker

Was bored so decided to write my own String Length function for NULL terminated strings. Hopefully willspark some interest in this ASM subsection, it's almost dead ;-P!

szLength PROC uses ESI ECX lpString:DWORD
 
 xor eax, eax
 mov ecx, lpString
 mov esi, lpString
 
 @@:
 inc esi
 cmp byte ptr [esi], 0
 jnz @B

 sub esi, ecx
 xchg eax, esi

 ret
 
szLength ENDP
