- Hi,
-
- I have to implement a module for file locking under msdos. Firstly
- the environment is dos 5.0 programming in "C" and compiling with
- Borland "C".
-
- The objective is as follows-:
-
- If a user or a process is using a file no other process or user
- should be allowed access to a file. There are two cases I want to consider
- the first one is in the case of networking if a process has placed
- this lock no other process or user should be allowed access to this file
- a message like "file currently locked by another user" should be
- printed. However if the process that has placed this lock executes a
- DOS shell and tries to access this file the same message should appear.
-
- If the machine is not on the network then if the user has
- placed a lock on a file and then executes a dos shell and tries to
- access this file the user should be denied access and the appropriate
- message should be printed.
-
- Any help would be greatly appreciated.
-
- Thanks,
-
- sabu.
