NAME    [Toc]    [Back]

     accf_data -- buffer incoming connections until data arrives

SYNOPSIS    [Toc]    [Back]

     options INET
     kldload accf_data

DESCRIPTION    [Toc]    [Back]

     This is a filter to be placed on a socket that will be using accept() to
     receive incoming connections.

     It prevents the application from receiving the connected descriptor via
     accept() until data arrives on the connection.

     The ACCEPT_FILTER_DATA kernel option is also a module that can be enabled
     at runtime via kldload(8) if the INET option has been compiled into the

EXAMPLE    [Toc]    [Back]

     Assuming ACCEPT_FILTER_DATA has been included in the kernel config file
     or the accf_data module has been loaded, this will enable the data accept
     filter on the socket sok.

	     struct accept_filter_arg afa;

	     bzero(&afa, sizeof(afa));
	     strcpy(afa.af_name, "dataready");
	     setsockopt(sok, SOL_SOCKET, SO_ACCEPTFILTER, &afa, sizeof(afa));
