returns. If the verb returns IN_PROGRESS to indicate
asynchronous completion, it is traced when it
completes. The top of each section of tracing shows the
name of the LUA verb issued and the result on its
return (taken from the primary and secondary return
codes). Any data being sent or returned 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
LUA Programmers Guide.
CPI-C
Because SNAplus2 implements CPI-C using APPC, the
CPI-C library converts most CPI-C calls into the
corresponding APPC verbs. Therefore, CPI-C tracing
includes both the CPI-C parameters and the APPC
parameters. First, the CPI-C request is traced, then
the APPC request, then the APPC return, and finally
the CPI-C return. For other CPI-C functions that deal
only with local information (such as checking or setting
the receive type or the synchronization level), no APPC
verbs are executed, so the tracing shows only the CPI-C
parameters.
The top of each section of tracing shows the name of the
CPI-C call or APPC verb issued and its return code.
Any data beingsent or returnedis also traced following
the CPI-C parametersor APPC verb control block, with
the address at which the data is stored.
For more information, refer to the HP-UX SNAplus2
CPI-C Programmers Guide.
HLLAPI
The following parameters for each HLLAPI function
are traced when the function is issued and again when
it returns:
func_number
Shown in parentheses after the name of the function.
data_length
and
ps_position/return code
