CASyncSocket::Socket

Allocates a socket handle.

BOOL Socket(
   int nSocketType = SOCK_STREAM,
   long lEvent = FD_READ | FD_WRITE | FD_OOB | FD_ACCEPT | FD_CONNECT | FD_CLOSE,
   int nProtocolType = 0,
   int nAddressFormat = PF_INET
);

Parameters

  • nSocketType
    Specifies SOCK_STREAM or SOCK_DGRAM.

  • lEvent
    A bitmask that specifies a combination of network events in which the application is interested.

    • FD_READ: Want to receive notification of readiness for reading.

    • FD_WRITE: Want to receive notification of readiness for writing.

    • FD_OOB: Want to receive notification of the arrival of out-of-band data.

    • FD_ACCEPT: Want to receive notification of incoming connections.

    • FD_CONNECT: Want to receive notification of completed connection.

    • FD_CLOSE: Want to receive notification of socket closure.

  • nProtocolType
    Protocol to be used with the socket that is specific to the indicated address family.

  • nAddressFormat
    Address family specification.

Return Value

Returns TRUE on success, FALSE on failure.

Remarks

This method allocates a socket handle. It does not call CAsyncSocket::Bind to bind the socket to a specified address, so you need to call Bind later to bind the socket to a specified address. You can use CAsyncSocket::SetSockOpt to set the socket option before it is bound.
