int memp_fset(DB_MPOOLFILE *mpf, void *pgaddr, u_int32_t flags);
The memp_fset function sets the flags associated with the page to which pgaddr refers without unpinning it from the pool. The pgaddr argument must be an address previously returned by memp_fget.
The flags value must be set to 0 or by bitwise inclusively OR'ing together one or more of the following values:
The DB_MPOOL_CLEAN and DB_MPOOL_DIRTY flags are mutually exclusive.
The memp_fset function returns a non-zero error value on failure and 0 on success.
The memp_fset function may fail and return a non-zero error for the following conditions:
The memp_fset function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions. If a catastrophic error has occurred, the memp_fset function may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
