For more details of the link_address structure and the port-specific and
link-specific data, see “DEFINE_PORT” and
“DEFINE_DLC”port_def_data. The data structure for the port-specific
data follows the
structure, and the data structure for the link-specific data follows this;
both structures are padded to start on a 4-byte boundary.
Supplied Parameters
The application supplies the following parameters:
opcode
AP_QUERY_PORT
overlay_size
For compatability with future releases of SNAplus2,
your application must use this field to determine the
exact length of the overlay structure returned, and
should not rely on the use of the sizeof() function.
buf_ptr
A pointer to a data buffer that SNAplus2 will use to
return the requested information.
buf_size
Size of the supplied data buffer.
