CBL_SRV_SERVICE_FLAGS

Syntax:

call CBL_SRV_SERVICE_FLAGS_SET using by value service-flags-mask
                                     by value service-flags
                                    returning status-code

Parameters

service-flags-mask: Call prototype (see Key): cblt-x4-comp5; Picture: pic x(4) comp-5.
service-flags: Call prototype (see Key): cblt-x4-comp5; Picture: pic x(4) comp-5.
status-code: See Library Routines - Key.

On Entry:

service-flags-mask

Mask that specifies the bit flags to be changed:

Bit 0

Value	Meaning
0	None
1	Commit transactional resources during successful service termination

Bit 1

Value	Meaning
0	None
1	Rollback transactional resources during successful service termination.

service-flags

Service control flags:

Bit 0

Value	Meaning
0	None
1	Commit transactional resources during successful service termination

Bit 1

Value	Meaning
0	None
1	Rollback transactional resources during successful service termination.

Bits 0 and 1 are treated as a bit pair and only relate to container-managed services. If neither bit is set, at service termination the run-time system will commit transactional resources if the service completes successfully, otherwise it will rollback transactional resources.

Attempting to set both bits 0 and 1 will be treated as an error; attempting to set either bit 0 or bit 1 by an application-managed service will also be treated as an error.

Bits 2-30

Reserved for future use

Bit 31

Value	Meaning
0	The service has not dirtied the COBOL container.
1	The service has dirtied the COBOL container and will result in the SEP being terminated following service termination.

On Exit:

status-code

0	Success
1009	Invalid parameter passed to the API
1015	Not running within the COBOL container
1016	Can only set commit/rollback flags when container managed

Example

copy "cblproto.cpy".
