The only way to know the file has been completely written is to have the writing process signal success in some way. Because only the writing process knows if it has successfully written all the data supposed to be in the file. The receiving process can not infer that accurately because of failure conditions, so any method based on timestamps or something similar can not be guaranteed to work.
Period.
Renaming the file is probably the best way to do that.
There are some kludges you can use on Solaris using the utssys() call that will return the process IDs of process that have any file open, but that will just tell you the file is open and won't tell you why the process has the file open, nor why it closed it. Look at the "sys/utssys.h" header file.
If you can find the source code for the Solaris "fuser" utility, you can see an example of how to use it.
Or you can run the "fuser" utility in a subprocess using system() or popen().
