Thanks, I Read this..
I tried this now:

            getbuffer();
                        int i;
                        int div=0;
                        int DataSent;

                        i = tcp_write(pcb, SndBuffer , SndBufferLen, 0);
                        tcp_output(pcb);
                        while(i == -1){
                                SndBufferLen /= 2;
                                div++;
                                i = tcp_write(pcb, SndBuffer , SndBufferLen, 0);
                                tcp_output(pcb);
                        }
                        DataSent = SndBufferLen;
                        int j;
                        int in=0;

                        for (j=1; j < (div); j++){
                                in=0;
                                i = tcp_write(pcb, SndBuffer+DataSent, 
SndBufferLen, 0);
                                tcp_output(pcb);
                                if (i == 0){
                                        DataSent += SndBufferLen;
                                }
                                while(i == -1){
                                        SndBufferLen /= 2;
                                        div++;
                                        i = tcp_write(pcb, SndBuffer+DataSent, 
SndBufferLen, 0);
                                        tcp_output(pcb);
                                        in=1;
                                }
                                if (in == 1){
                                        DataSent += SndBufferLen;
                                }
                        }







But didnt Work too ;/
