Dear all,
I have one application(processA) is writting one file.
And , I create another application(processB) which want to know that if processA are writting the file.
I know the Window MFC use CFile* file->open(fileName , CFile::shareDenyWrite) , it can return FALSE if the file is being written by processA.
On Mac OS side. i try some method to do it . but all false .
1. use open(fileName , O_SHLOCK , O_RDWR)
2. use FSOpenFork
3. NSFileManager
How can i do? Waiting for you help.Thanks a lot.
Thank you!
