[Iaxclient-devel] solved struct hell.

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

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=0;
 unsigned int lastsent;
 unsigned int fts;

#ifdef _MSC_VER
 buffer[0]=0;
#else
 /* Shut up GCC */
 buf.buffer[0] = 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.
