User exit routine UCCWLOG is called at the point where writing a record to
the log buffer has been completed (if the WLOG exit point is active).
Exit point WLOG is in copy segment CL20 of CSECT CCTLOG.
General Conditions at Entry
The registers at entry to UCCWLOG are:
- R1
- Pointer to the WLOGC CONTROL structure.
- R2
- Pointer to the WLOGC DATALIST structure.
- R7
- Pointer to the WLOGC parameter list.
- R8
- Base of the E-type program that issued the request.
- R9
- Address of the entry control block (ECB).
- R11-R15
- See User Exit Routines - Common Entry Conditions.
System Conditions at Entry
- System state
- Supervisor
- System mask
- Masked for I/O
- Protect key
- Zero (0)
- Address space
- EVM or SVM.
Programming Considerations at Entry
- The entry address space, SVM or EVM, depends on the address space of the
caller of WLOGC. WLOGC can be called from either real-time or CP
code.

- See User Exit Routines - Common Programming Considerations for other considerations.
