SockIOBlock ISOCKET_Read() ISOCKET_Write() ISOCKET_WriteV()
This function reads data from a socket into one or more buffers described by the entries in the iov[] array. This function always returns immediately. If there is no data available and the connection is still active, ISOCKET_ReadV() returns AEE_NET_WOULDBLOCK. To be notified when to call ISOCKET_ReadV() again, the caller must call ISOCKET_Readable().
Pointer to the ISocket Interface object.
Array of SockIOBlock structures into which data can be read.
Specifies the number of entries in the iov array.
  •     int32 ISOCKET_ReadV
        ISocket * pISocket,
        SockIOBlock iov[],
        uint16 iovcount
  • bytes_read, any positive number indicates the number of bytes that have been successfully read into the provided buffer.
    0 (zero), if there is no more data to be received; the peer has shut down the connection.
    AEE_NET_WOULDBLOCK, if no data available now; try again later (See ISOCKET_Readable()).
    AEE_NET_ERROR, if the socket is not in a valid state to receive data.
Side Effect
  • None.
The specific error code can be retrieved by calling ISOCKET_GetLastError(). The error codes returned include: AEE_NET_EBADF Invalid socket descriptor is specified. AEE_NET_ECONNABORTED TCP connection aborted because of a time-out or other failure. AEE_NET_ECONNRESET TCP connection reset by server. AEE_NET_EFAULT Application buffer not valid part of address space. AEE_NET_EIPADDRCHANGED IP address changed, causing TCP connection reset. AEE_NET_ENETDOWN Network subsystem unavailable. AEE_NET_ENOTCONN Socket not connected. AEE_NET_EPIPE Broken pipe. AEE_NET_EWOULDBLOCK Operation would block. AEE_NET_GENERAL_FAILURE General failure. AEE_NET_ESHUTDOWN Connection is shutdown for reading.
