This function creates a socket that is bound to a specific service provider.

Note

This function is actually a Winsock function. However, the information that is presented in it is specific to Bluetooth.

Syntax

SOCKET socket(
  int af,
  int type,
  int protocol
);

Parameters

  • af
    [in] Address family specification. To create a Bluetooth socket, use: af = AF_BTH

  • type
    [in] Type specification for the new socket. To create a Bluetooth socket, use:

    type = SOCK_STREAM

  • protocol
    [in] Protocol to be used with the socket that is specific to the indicated address family. To create a Bluetooth socket, use:

    protocol = BTHPROTO_RFCOMM

Return Value

If no error occurs, this function returns a descriptor referencing the new socket. If an error occurs, a value of INVALID_SOCKET is returned, and a specific error code can be retrieved by calling WSAGetLastError.

Remarks

The following example code shows how to use socket to create a Bluetooth socket.

SOCKET s = socket (AF_BTH, SOCK_STREAM, BTHPROTO_RFCOMM);

For more information about the socket function, see socket (Windows Sockets) in the Winsock reference.
