3.118.2 Supplied Parameters
The application supplies the following parameters:
opcode
AP_QUERY_DOWNSTREAM_PU
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 downstream PUs for which data should be returned. To request data for a specificPU
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. Possible values are:
AP_FIRST_IN_LIST
Start at the first entry in the list.
AP_LIST_INCLUSIVE
Start at the entry specified by the dspu_name parameter.
