Because FPUTFGET does not support read locks, it now promotes read lock requests to write lock. Before this upgrade, the function that acquired a read lock, did nothing but return success. This could cause problems for an application that used LKISAM() with the ctREADREC or ctREADREC_BLK mode in the FPUTFGET model because no locks were actually acquired.
In FPUTFGET mode, LKISAM() now converts read lock requests (ctREADREC and ctREADREC_BLK lock modes) to write lock requests (ctENABLE and ctENABLE_BLK lock modes).
