libdcwsocket -- Dual-channel Wi-Fi control/signalling socket library.


This library is used to receive and transmit DCW control/signalling packets on
the primary channel interface.



API Usage Examples:

  . To open a DCW control socket and listen for packets:

    #include <dcwsocket.h>
    #include <stdio.h>

    static void
    dump_buf(const unsigned char * buf, unsigned size) {
      fprintf(stderr, "dump_buf:");
      for(; size--; buf++) {
        fprintf(stderr, " %02hX", (unsigned short)*buf);
      }
      fprintf(stderr, "\n");
    }

    void example_dcw_recv_test( void ) {
      dcw_socket_t s;
      unsigned char buf[10240];
      int rv;

      s = dcwsock_open("wlan0");
      if (s == NULL) return; /* failed */

      /* wait forever to receive a DCW message on interface "wlan0" */
      rv = dcwsock_recv(s, buf, sizeof(buf));
      if (rv == -1) {
        dcwsock_close(s);
        return; /* failed */
      }

      /* dump the raw contents (hex) of the received message */
      dump_buf(buf, (unsigned)rv);

      /* cleanup */
      dcwsock_close(s);
    }
