Struc

[Rage9]

I have a struc

Code Select Expand



sClient STRUC

param1 OVERLAPPED <>
param2 WSABUF <>

param3 DWORD ?
.
.
.
.

sClient        ENDS



and another variable

Code Select Expand


vAccept WSAEVENT <>



Fore some reason or another the compiler doesn't like the WSAEVENT and WSABUF data types.  Is there something I have to include to get these to work right?  Maybe some definition file?


Furthermore I pass this Struct to a couple procedures, however the compiler doesn't like:

Code Select Expand


AddClient proto stdcall :sClient


Instead compiler returns errors:

Code Select Expand


(40) : error A2006: undefined symbol : sClient
(40) : error A2195: parameter or local cannot have void type
(40) : error A2131: VARARG parameter requires C calling convention



Any help would be awesome.

Thanks in advance.

Try it with the MASM form STRUCT. From memory STRUC is a TASM leftover.

[Rage9]

Changed it to STRUCT makes no difference as it still doesn't like that WSABUF

[Rage9]

Here are my includes just in case your wondering if I have something included

Code Select Expand


include  c:\masm32\include\windows.inc
include c:\masm32\include\kernel32.inc
include c:\masm32\include\user32.inc
include c:\masm32\include\ws2_32.inc ; the winsock 2 include

includelib c:\masm32\lib\kernel32.lib
includelib c:\masm32\lib\user32.lib
includelib c:\masm32\lib\ws2_32.lib ; the winsock 2 library

What you need to do is see if the structures you are calling exist. It would appear that your "sClient" structure is defining other structures which may not be available.

WSABUF and WSAEVENT are declared in winsock2.h

Code Select Expand


#define WSAEVENT                HANDLE
typedef struct _WSABUF {
    u_long      len;     /* the length of the buffer */
    char FAR *  buf;     /* the pointer to the buffer */
} WSABUF, FAR * LPWSABUF;

Code Select Expand

AddClient proto stdcall :sClient
should be

Code Select Expand

AddClient proto stdcall :PTR sClient
or just

Code Select Expand

AddClient proto stdcall :DWORD

Thanks so much sinsi, I just put :PTR in and it worked like a charm.

However still not understanding what I need to do to get WSABUF and WSAEVENT to work correctly.

Am I suppose to include winsock2.h?

Thanks in advance.

Hello!

Code Select Expand

WSABUF STRUCT
  len    DWORD   ?
  buf   DWORD   ?
WSABUF ENDS

WSAEVENT  TEXTEQU   <DWORD>

You should add this to your code. I can't seem to find those in masm32 include files ...

Nick

Thanks much TNick!

Having a few more problems yet:

I have a global array:

Code Select Expand


gClientArray sClient MAX_CLIENTS dup (<?>)


Of course sClient is the STRUCT and MAX_CLIENTS equ 10000.

2 questions on this,
1.  Why am I getting errors on compile about this?

Code Select Expand


(82) : error A2181: initializer must be a string or single item
(82) : error A2138: invalid data initializer


2.  Is there a way to make this dynamic?  Thus no need to set a max amount?


-----------------


I've got this is a situation:

Code Select Expand



local lClient:sClient,
       lpKey:DWORD

ASSUME ebx:PTR sClient

lea ebx, lClient
lea edx, gClientArray ;array of sClient STRUCT


lpKey will hold a key that will identify a client
ecx holds our counter

need to test gClientArray[ecx].mkey to lpKey
would it be like this

Code Select Expand


cmp (sClient PTR [edx][ecx]).mKey, lpKey


Not sure why I ask if it's right, because the compiler does not like it.

Then I need to move the entry, when found, from the global array to the local

-------------


Finally at some point and time I need to remove the clients info when they disconnect.

I just pass the number of it's global array position, but what would be the best way to zero it out?  Xor?  RtlZeroMemory?



Thanks much.

I figured out everything except that first part with gClientArray.  For some reason or another.

Played around with it, took out the ? and it worked WOOO! :U
