SYNOPSIS

options INET options ACCEPT_FILTER_DATA kldload accf_data

DESCRIPTION

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 kernel.

EXAMPLES

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));
