NOF API Verbs
QUERY_DLUR_PU
dlus_name
DLUS name for which PU information is required. To list only information about PUs associated with a
specific DLUS, specify the DLUS name; a PU will be listed only if it has an SSCP-PU session to the speci
fied
DLUS node. To obtain a complete list for all DLUSs, set this field to binary zeros.
The name is a 17-byte EBCDIC string, right-padded with EBCDIC spaces. It consists of a network ID of
up to 8 A-string characters, an EBCDIC dot (period) character, and a network name of up to 8 A-string
characters.
filter
Specifies whether to filter the returned PUs according to their location.
Allowed values for network node are:
AP_INTERNAL
Return information only for internal PUs.
AP_DOWNSTREAM
Return information only for downstream PUs.
AP_NONE
Return information about all PUs irrespective of location.
For end node, this parameter is reserved (downstream DLUR PUs are not supported).
3.114.3 Returned Parameters: Successful Execution
If the verb executes successfully, SNAplus2 returns the following parameters:
primary_rc
AP_OK
buf_size
Length of the information returned in the supplied buffer.
total_buf_size
Returned value indicating the size of buffer that would have been required to return all the list information
requested. A value greater than
buf_size indicates that not all the available entries were returned.
num_entries
Number of entries returned in the data buffer.
total_num_entries
Total number of entries available. A value greater than num_entries indicates that not all the available entries
were returned.
Each entry in the data buffer consists of the following parameters:
dlur_pu_summary.overlay_size
The size of the returned
dlur_pu_summary structure, and therefore the offset to the start of the next entry in the
data buffer.
When your application needs to go through the returned buffer to find each
dlur_pu_summary structure in
turn, it must use this value to move to the correct offset for the next data structure, and must not use the
C
sizeof() operator. This is because the size of the returned overlay may increase in future releases of
SNAplus2; using the returned overlay size ensures that your application will continue to work with future
releases.
