NAME sam_set_fs_thresh - Sets file system thresholds for the releaser SYNOPSIS cc [ flag ... ] file ... -L/opt/SUNWsamfs/lib -lsamapi [library ... ] #include "/opt/SUNWsamfs/include/samapi.h" int sam_set_fs_thresh(ushort_t eq_number, int min_threshold, int max_threshold, int wait_response); DESCRIPTION sam_set_fs_thresh() sets the minimum (low) and maximum (high) thresholds which control the execution of the releaser for archived files in the family set at equipment number eq_number. Reaching the maximum threshold in the fam- ily set initiates the releaser, which releases file space until the minimum threshold is reached or no release candi- dates exist. The call will return immediately after issuing the command if zero is specified for wait_response value. Other values for wait_response will give undefined results. RETURN VALUES Upon succesful completion a value of 0 is returned. Other- wise, a value of -1 is returned and errno is set to indicate the error. ERRORS sam_set_fs_thresh() fails if one or more of the following are true: ER_DEVICE_NOT_CORRECT_TYPE The specified eq_number device is not a family set device. ER_FIFO_PATH_LENGTH The path and filename for the FIFO pipe is too long. ER_NO_EQUIP_ORDINAL eq_number is not a defined equipment number in this configuration. ER_NO_MASTER_SHM No Sun QFS or SAM-QFS master shared memory segment defined. Check that the Sun QFS or SAM-QFS file systems are mounted. ER_NO_MASTER_SHM_ATT No Sun QFS or SAM-QFS master shared memory segment found. Check that the Sun QFS or SAM-QFS file systems are mounted. ER_NO_RESPONSE_FIFO Unable to create the response FIFO pipe.
