For more details of the
link_address structure, see Section 3.129, QUERY_LS; for more details of the port-specific
and link-specific data, see Section 3.39, DEFINE_PORT and Section 3.29, DEFINE_LS. The data structure for the
port-specific data follows the
port_def_data structure, and the data structure for the link-specific data follows this;
both structures are padded to start on a 4-byte boundary.
3.149.2 Supplied Parameters
The application supplies the following parameters:
opcode
AP_QUERY_PORT
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.
num_entries
Maximum number of ports for which data should be returned. To request data for a specific port rather than
a range, specify the value 1. To return as many entries as possible, specify zero; in this case, SNAplus2 will
return the maximum number of entries that can be accommodated in the supplied data buffer.
list_options
The position in the list from which SNAplus2 should begin to return data, and the level of information required
for each entry. Specify the level of information with one of the following values:
AP_SUMMARY
Summary information only.
AP_DETAIL
