Turns LDB write-through on or off for all LDBs

int sm_dd_able(int flag);

Specifies whether to turn LDB processing on or off:


Turn processing off; no data is exchanged between screens and LDBs.


Turn processing on for all LDBs loaded into memory.


sm_dd_able enables or disables data exchange between screens and all loaded LDBs according to the value of flag.

Individual LDBs can have their write-through capability selectively turned on or off via sm_ldb_state_set, but attempting activate write-through for an LDB will not work if sm_dd_able has already been called to turn processing off for all loaded LDBs.

For more information about LDB processing, refer to "Using Local Data Blocks" in Application Development Guide.
