'Client socket coded in ASM (FASM) does not connect to Server
I am creating a communication between a client and a server via tcp/ip socket. I am developing the client in ASM (FASM) and I cannot connect to the server.
The client code in assembler:
include 'win32ax.inc'
.data
; Variables
address db '127.0.0.1', 0
port dd 2222
wsa WSADATA ?
s dd ?
sdr sockaddr_in ?
conec hostent ?
start :
; Initialising Winsock
push wsa
push 200
call [WSAStartup]
;cmp eax, 0
; Creating a socket
push 0
push 1
push 2
call [socket]
;cmp eax, -1
mov [s], eax
; Connect to a Server
push address
call [gethostbyname]
mov [conec],eax
push [port]
call [htons]
mov [sdr.sin_family], 2
mov [sdr.sin_port], ax
mov eax,[conec]
mov [sdr.sin_addr], eax
push 20
push sdr
push [s]
call[connect]
.end start
Suggestions and improvements are welcome. Thanks.
