[asterisk-dev] asterisk how to use zaptel

[张留祺]

Hi,all!
   Now,I want use zaptel to my own program,just like asterisk use zaptel! When a write a simple test,I found a problem!It's that: I use the TDM410p card and loop the span2 and span4,then I write the channel 32 and read the data from channel 94,the code like this: 
write.c
for(;;)
{
//         fd is the value of func open return it point channel 32;buffer is memset(buffer,'a',1023);buffer[1023]='\0';
           write(fd,buffer,1024);
}
 
read.c
for(;;)
{
//         fd is the value of func open return it point channel 94;readbuffer is filled with 0;
           read(fd,readbuffer,1024);
}
then , the function read return 1024,and i use printf("%s",readbuffer); I found when i send 1023 'a',i recieve 1023 'a',but in twice,the first package with lots of 0xff and some 'a',the second package filled parts of 'a'.
 How can i once recieve the 1023 'a'? Can any one help me ?
