NAME dce_db_header_fetch - Retrieves the header from a backing store SYNOPSIS #include <dce/dce.h> #include <dce/dbif.h> void dce_db_header_fetch( dce_db_handle_t handle, void *key, dce_db_header_t *hdr, error_status_t *status ); PARAMETERS Input handle A handle, returned from dce_db_open(), that identifies the backing store being used. key A string or UUID that is the backing store key. Output hdr A pointer to a caller-supplied header structure to be filled in by the library. 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_header_fetch() routine returns a pointer to a copy of the header of the object in the backing store that is identified by the handle parameter, which was obtained from dce_db_open(). The caller must free the copy's storage. It was allocated (as with other fetch routines) through rpc_ss_alloc(). The key parameter is interpreted according to the type of index with which the backing store was created. The hdr parameter is shown as a pointer to an arbitrary data type. In actual use it will be the address of the backing-store-specific data type. ERRORS db_s_key_not_found The key was not found in the backing store. error_status_ok The call was successful.
