Tracing
Chapter 3 87
APPC, NOF, MS
The verb control block supplied by the application to
the corresponding API library is traced when the verb
is issued and when it returns. For verbs issued through
the asynchronous entry point and for the APPC
[MC_]RECEIVE_AND_POST verb issued using the
synchronous entry point, both the initial return
(indicating that the verb was issued successfully and is
in progress) and the return to the callback routine
(when the verb completes) are traced.
The top of each section of tracing shows the name of the
verb issued and the result on its return (taken from the
primary return code). Any data being sent or returned
is also traced following the verb control block (VCB),
with the address at which the data is stored (taken
from the verb control block).
If an MS or NOF application has registered to receive
indications, each indication is also traced in a format
similar to an asynchronous verb return.
For information about the VCB structures and content
for each of these APIs, refer to the HP-UX SNAplus2
APPC Programmers Guide, HP-UX SNAplus2 NOF
Programmers Guide, and HP-UX SNAplus2 MS
Programmers Guide.
CSV
The verb control block supplied to the CSV library is
traced when the verb is issued and when it returns.
The top of each section of tracing shows the name of the
verb issued and the result on its return (taken from the
primary return code). Any data string included in a
verb is also traced following the verb control block with
the address at which the data is stored (taken from the
verb control block).
For more information, refer to the HP-UX SNAplus2
CSV Programmers Guide.
LUA
The verb control block supplied to the LUA library is
traced when the verb is issued and again when it
