| ## dce_db_store_by_uuid(3dce) Stores data into a UUID-indexed backing store Synopsis #include <dce/dce.h> #include <dce/dbif.h> void dce_db_store_by_uuid( dce_db_handle_t handle, uuid_t *key, void *data, error_status_t *status); Parameters Input handle A handle, returned from dce_db_open( ), that identifies the backing store being used. key A UUID that is the backing store key. data A pointer to the data structure to be stored. Output status A pointer to the completion status. On successful completion, the routine returns error_status_ok. Otherwise, it returns an error. Description The dce_db_store_by_uuid( ) routine stores the data structure pointed to by data into the backing store. The conversion function that was specified in the call to dce_db_open( ) serializes the structure so that it can be written to disk. This routine is specialized for storage into backing stores that are indexed by UUID, as selected by the db_c_index_by_uuid bit in the flags parameter to dce_db_open( ) when the backing store was created. If the key value is the same as a key already stored, the new data replaces the previously stored data associated with that key. Notes Because the dce_db_store_by_uuid( ) routine uses the encoding services, and they in turn use rpc_sm_allocate( ), all programs that call dce_db_store_by_uuid( ) outside of a server operation (for instance, if a server does some backing store initialization, or in a standalone program) must call rpc_sm_enable_allocate( ) first. Indeed, every thread that calls dce_db_store_by_uuid( ) must do rpc_sm_enable_allocate( ), but in the server side of an RPC, this is already done. Errors The following describes a partial list of errors that might be returned. Refer to the OSF DCE Problem Determination Guide for complete descriptions of all error messages. db_s_bad_index_type The backing store is not indexed by UUID. db_s_readonly The backing store was opened with the db_c_readonly flag, and cannot be written to. db_s_store_failed The data could not be stored into the backing store for some reason. The global variable errno may contain more information about the error. db_s_iter_not_allowed The function was called while an iteration, begun by dce_db_iter_start( ), was in progress. Storing is not allowed during iteration. error_status_ok The call was successful. Related Information Functions: dce_db_open(3dce) dce_db_store(3dce) dce_db_store_by_name(3dce) ##
