    NAME

    shutdown - shut down socket send and receive operations
     
    

    SYNOPSIS

    #include <sys/socket.h>

    int shutdown(int socket, int how);
     

    DESCRIPTION

    The shutdown() function shall cause all or part of a full-duplex connection on the socket associated with the file descriptor socket to be shut down.

    The shutdown() function takes the following arguments:

    socket
    Specifies the file descriptor of the socket.
    how
    Specifies the type of shutdown. The values are as follows:
    SHUT_RD
    Disables further receive operations.
    SHUT_WR
    Disables further send operations.
    SHUT_RDWR
    Disables further send and receive operations.

    The shutdown() function disables subsequent send and/or receive operations on a socket, depending on the value of the how argument.  

    RETURN VALUE

    Upon successful completion, shutdown() shall return 0; otherwise, -1 shall be returned and errno set to indicate the error.  

    ERRORS

    The shutdown() function shall fail if:

    EBADF
    The socket argument is not a valid file descriptor.
    EINVAL
    The how argument is invalid.
    ENOTCONN
    The socket is not connected.
    ENOTSOCK
    The socket argument does not refer to a socket.

    The shutdown() function may fail if:

    ENOBUFS
    Insufficient resources were available in the system to perform the operation.
