Hello All, I have written a utility in c on unix that will show all locked records in a C-ISAM file. This has worked a treat, until we upgraded to C-ISAM 5. The program now returns with no lock information. How has the locking changed in C-ISAM from version 3 to 5+ ? I am using fcntl() on the UNIX machine to check for locks, with a locking table offset of 0x40000000L - is this what has changed ? if so what has it changed to ? Any help would be much appreciated. Regards, Robin Grayson.
