Note
The DLUR_LU_DETAIL structure may be followed by a Route Selection Control Vector
(RSCV) as defined by SNA Formats. This control vector defines the session route through
the network and is carried on the BIND. This RSCV is included only if the node’s
configuration (specified using DEFINE_NODE) indicates that RSCVs should be stored
for DLUR sessions and if the PLU-SLU session is active.
3.113.2 Supplied Parameters
The application supplies the following parameters:
opcode
AP_QUERY_DLUR_LU
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 DLUR LUs for which data should be returned. To request data for a specific LU 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.
