filelocking

[rko]

hi all,
is there anyway to do filelocking with pb? if not, is there some src for the win api that allows that?

thank in advance for any help.

What do you mean? The file is locked automatically if you open it for writing with CreateFile() or OpenFile. You don't need to do this manually.

more than one process will open a file and read and write it. i would ike to get something like share and un/lock region.

It depends entirely on exactly what you wish to do - if for example you mean files that are only opened by your application and you wish them to be locked to prevent other Users of your application from trying to open an already open file, you can use a simple record db that has a list of open files and have the app check/update the list accordingly. On the other hand, if you are trying to stop file access by any application to a common file type like a text file, then you need a 'vault' arrangement where the User has to request access to a file.

There's posts in these forums with how to do it. Do a search.
Also, this isn't a Trick or Tip, so can a mod please move it to
Coding Questions.

PureBasic standard file commands don't open files for sharing. You'll have to go the 'Api' way... sorry.
