It is the responsibility of the application to determine
if data is in the class that should be cleared when freed. Knowledge
of the confidential text and encryption options in effect for a session
is available to applications by examining the RPLTCRYP and RPL6CFTX
fields in the RPL. To clear CSM storage, the application specifies
the CLEAR parameter on an IVTCSM request.
- For an HPDT send operation, the application specifies the CLEAR
parameter when it obtains the buffers on the IVTCSM REQUEST=GET_BUFFER
macroinstruction.
- For an HPDT receive operation, the application specifies the CLEAR
parameter when it frees the buffers on the IVTCSM REQUEST=FREE_BUFFER
macroinstruction.
The storage is not cleared until it is returned to the
pool.
