SIOCSAPPLDATA input

Input is provided using a pointer to a SetApplData structure, which in turn defines the version, size, and location of the SetADcontainer structure that contains the application data to be associated with the stream socket.

Table 1. SetApplData
Field name	Size	Description
SetAD_eye1	8	constant SETADEYE1
SetAD_ver	4	constant SETADVER
SetAD_len	4	sizeof(SetADcontainer)
SetAD_ptr	8	A bimodal pointer to a SetADcontainer structure. In 31-bit addressing mode the first 4 bytes are reserved and should be 0; the second 4 bytes contain the 31-bit address.

Table 2. SetADcontainer
Field name	Size	Description
SetAD_eye2	8	constant SETADEYE2
SetAD_buffer	40	A character buffer that contains the data to associate with this end of the connection. This buffer should be padded on the right with space characters.
