DESCRIPTION Function d_rlbtst will test the record lock bit of the current record to determine if it is set. Status code S_LOCKED is returned if the lock bit in the current record is set. Status S_UNLOCKED is returned if the lock bit of the current record is clear. It is not necessary to have locked the current record type.
This function is present in the single-user version of db_VISTA, but performs no action. This allows multi-user applications to link with the single user version for operation on stand-alone computer.
CURRENCY CHANGES None.
RETURN CODES
8 S_LOCKED Current record's lock bit is already set.
9 S_UNLOCKED Current record's lock bit is clear. The single- user version always returns an S_UNLOCKED status.
EXAMPLE /* ensure no info records are locked */ for (d_recfrst(INFO);db_status == S_OKAY; recnext(INFO)) { if ( d_rlbtst()== S_locked { /* report locked record */ ... /* clear locked record */ d_rlbclr(); } }
