I have many process wanting to write in a file. Each process is going to
open the file as a writeonly (using Assignfile and rewrite or fpOpen
with o_WrOnly). But there is a risk that two processes simultaneously
trying to write a message in the file. I want to use fpflock to avoid
this. Is it possible? What I done is something like this:
AssignFile (OutputFile, FileName);
fpflock (OutputFile, LOCK_EX);
The description of fpFlock does not say anything about the default
behavior of fpFlock (Is it blocking?). What I saw told me that it is not
Is it the correct way of using fpFlock?
