[Iaxclient-devel] solved struct hell

[Faizan N. <fai...@vo...>]

Hi.
Well it looks like Release version wont work for a while. So here is the
solution with some C theory.
If I am repeating someone's else thoughts than sorry for that.
/////////////////MY CODE//////////////////
#ifdef _MSC_VER
 unsigned buffer[4096];
        struct {
                struct iax_frame fr2;
        } buf;
#else
  struct {
   struct iax_frame fr2;
   unsigned char buffer[4096];             /* Buffer -- must preceed fr2 =
*/
        } buf;
#endif
 struct iax_frame *fr;
 int res;
 int sendmini=3D0;
 unsigned int lastsent;
 unsigned int fts;

#ifdef _MSC_VER
 buffer[0]=3D0;
#else
 /* Shut up GCC */
 buf.buffer[0] =3D 0;
#endif
/////////////////////////////////////////END OF MY
CODE.//////////////////////////////

The member afdata of iax_frame is zero sized. The struct hell origianly =
was
declaerd like this
////////////////code in iax_send/////////
struct hell
{
    struct iax_frame*fr2;
    unsigned char buffer[4096];
} buf;
////////////////end code///////
This allocated 4K after afdata so when afdata is filled it goes into =
buffer
but is able to accessed by afdata.
MSVC doesnt allow this. Putting it buffer before fr2 compiles fine but =
gives
no space for data to be copied in afdata.
So, remebering that stack is in reverse declaring buffer just before =
struct
hell gives afdata 4K like this.
//////////////modified iax_send code.///////////
unsigned char buffer[4096];
struct hell
{
    struct iax_frame*fr2;
} buf;
//////////////end code///////////////////////

I hope this solevs the proble,
Somebody get the Release version working.
thank you.
