Appendix BCommon Return Codes
A secondary return code is not returned.
B.22 AP_SVC_ERROR_TRUNC
The primary return code is:
primary_rc
AP_SVC_ERROR_TRUNC
In Send state, after sending an incomplete logical record, the partner TP (or partner LU) issued a
SEND_ERROR verb. The local TP may have received the first part of the logical record.
A secondary return code is not returned.
B.23 AP_THREAD_BLOCKING
WINDOWS
The primary return code is:
primary_rc
AP_THREAD_BLOCKING
The verb was issued using the APPC (blocking) entry point, but another blocking APPC verb was
already outstanding. For more information about these entry points, see Section 2.4, APPC Entry
Points: Windows Systems.
A secondary return code is not returned.
B.24 AP_TP_BUSY
The primary return code is:
primary_rc
AP_TP_BUSY
The local TP has issued a call to APPC while APPC was processing another call for the same TP.
This may occur if the local TP has started multiple processes, and more than one process is issuing
APPC calls using the same tp_id. However, ensure that each process issues its own TP_STARTED or
RECEIVE_ALLOCATE verb to obtain its own tp_id; the results of multiple processes using the same
tp_id are unpredictable.
WINDOWS
This return code may also indicate that the application issuing the verb was invoked using the Windows
function SendMessage instead of PostMessage; the application cannot issue any verbs in this
state. For more information, see Section 2.6, Windows Considerations.
