HP-UX SNAplus2 R7 NOF Programmer's Guide

NOF API Verbs
QUERY_MODE_DEFINITION
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:
mode_def_summary.overlay_size
The size of the returned
mode_def_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
mode_def_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.
mode_def_summary.mode_name
Mode name. This is an 8-byte type-A EBCDIC string, padded on the right with spaces if the name is shorter
than 8 characters.
mode_def_summary.description
A null-terminated text string describing the mode, as specified in the definition of the mode.
mode_def_detail.overlay_size
The size of the returned
mode_def_detail
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
mode_def_detail
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.
mode_def_detail.mode_name
Mode name. This is an 8-byte type-A EBCDIC string, padded on the right with spaces if the name is shorter
than 8 characters.
mode_def_detail.mode_chars.description
A null-terminated text string describing the mode, as specified in the definition of the mode.
mode_def_detail.mode_chars.max_ru_size_upp
Upper boundary for the maximum RU size to be used on sessions with this mode name. The value is used
when the maximum RU size is negotiated during session activation.
Range: 256–61,440. This field is ignored if the default_ru_size parameter (see below) is set to
AP_YES.
mode_def_detail.mode_chars.receive_pacing_win
Session pacing window for sessions using this mode. For fixed pacing, this is the maximum number of frames
that can be received from the partner LU before the local LU must send a response; for adaptive pacing, this
value is used as an initial receive window size. SNAplus2 always uses adaptive pacing unless the adjacent
node specifies that it is not supported.
