Hi,
I have tried to send this to the list, but it doesn't seem
to arrive (at least I have not got it back in my mail).

Subject: Report of problems found in ver 0.17.1


Hi all,
While enjoying myself with the task of porting linux code to Windows,
I found some minor problems.....

Here follows a list of source-code errors and/or problems needing a fix.
Not all of them are serious, but I hate it when my compiler says anything
but "WIN5250.exe - 0 error(s), 0 warning(s)" in the Build window.....

Source:
0.17.1 from CVS checkout 02-jun-2001

============================================================================
====================
Cosmetic:
c:\projekt\tn5250\linux\dbuffer.c(62) : warning C4101: 'n' : unreferenced

display.c
in function:
void tn5250_display_do_key(Tn5250Display *This, int key)
....
         tn5250_display_interactive_addch (This, key);
...

void tn5250_display_interactive_addch(Tn5250Display * This, unsigned char
ch)

Result:
c:\projekt\tn5250\linux\display.c(1029) : warning C4761: integral size
mismatch in argument; conversion supplied

change/cast line 1029 to:
         tn5250_display_interactive_addch (This, (unsigned char)key);

============================================================================
====================
stream.c/h
declaration in stream.h:
extern Tn5250Stream *tn5250_stream_host(SOCKET_TYPE masterSock, long
timeout, int streamtype);
implementation in stream.c:
       Tn5250Stream *tn5250_stream_host(int masterfd, long timeout, int
streamtype)

Result:
C:\Projekt\tn5250\Linux\stream.c(161) : warning C4028: formal parameter 1
different from declaration

All sockets should be of type SOCKET_TYPE.
------
Missing declaration of tn3270_telnet_stream_init
/* External declarations of initializers for each type of stream. */
extern int tn5250_telnet_stream_init (Tn5250Stream *This);
extern int tn3270_telnet_stream_init (Tn5250Stream *This);   <<--ADD THIS TO
FIX

Result:
C:\Projekt\tn5250\Linux\stream.c(177) : error C4013:
'tn3270_telnet_stream_init' undefined; assuming extern returning int

============================================================================
====================
telnetstr.c
declaration:
static int telnet_stream_accept(Tn5250Stream * This, SOCKET_TYPE
masterSock);
implementation:
static int telnet_stream_accept(Tn5250Stream * This, int masterfd)
Result:
C:\Projekt\tn5250\Linux\telnetstr.c(456) : warning C4028: formal parameter 2
different from declaration

All sockets should be of type SOCKET_TYPE.
------
This->options = This->options | (1 << sb_buf[i]+1);
C:\Projekt\tn5250\Linux\telnetstr.c(878) : warning C4554: '<<' : check
operator precedence for possible error; use parentheses to clarify
precedence
Hmmm. You tell me, I don't know without reading the TN3270E specification if
it should be (1 << (sb_buf[i]+1) )
------
      tn5250_buffer_append_byte(&out_buf, header.h3270.sequence >> 8);
      tn5250_buffer_append_byte(&out_buf, header.h3270.sequence & 0x00ff);

void tn5250_buffer_append_byte( Tn5250Buffer* This, unsigned char b )
int sequence;
Should be ( I think):
      tn5250_buffer_append_byte(&out_buf, (unsigned
char)(header.h3270.sequence >> 8) );

============================================================================
====================
terminal.c
void tn5250_terminal_beep (Tn5250Terminal *This)
{
   return (* ((This)->beep)) ((This));
}
C:\Projekt\tn5250\Linux\terminal.c(67) : warning C4098:
'tn5250_terminal_beep' : 'void' function returning a value
============================================================================
====================
============================================================================
====================
Huge memory leak!
I have not found any code that actually calls
lib5250/tn5250_display_destroy() ,
and when I ported the code to WIN32, BoundsChecker filled my screen with
memory leaks.....

bomb_out:

        if (term != NULL)
        {
                tn5250_terminal_term(term);
        }
// Add this code, ------------------------------------------------
// to release all the memory used by the display object, and the
//  terminal object, it's displaybuffer(s) a.s.o.

        if (display != NULL)
        {
                tn5250_display_destroy(display); // dbuffer(s), terminal
        }
// --------------------------------------------------------------
        if (sess != NULL)
        {
                tn5250_session_destroy(sess);
        }
        else if (stream != NULL)
        {
                tn5250_stream_destroy (stream);
        }

        if (config != NULL)
        tn5250_config_unref (config);
============================================================================
====================

End of list (for now)
