How you use the lockfile ?

function LockFile(hFile: THandle; dwFileOffsetLow, dwFileOffsetHigh: DWORD;
nNumberOfBytesToLockLow, nNumberOfBytesToLockHigh: DWORD): BOOL; stdcall;

I would like to know how to use this function in delphi ?

Bye

This function locks a portion of a file. You pass handle of the file, start offset (64bit), and number of bytes (64bit) to lock as parameter. That's all.

The only thing you have to consider is that when you open or create the file, do not deny any sharing. Otherwise, the entire file is already locked.
