fopen ("file on shared drive","w+") doesn't work on 2nd call   

Hello, 

I have a shared drive on SGI, Linux, and Windows. The fact that I'm 
using a shared drive may be mute information. 

The problem is within the same program a second call to fopen does not 
create a file if the file has been deleted. 

I would like to use fopen for its pointer return value to solve this. 

What is the best way to fix this problem? 

The reason I want to do this is I do not want to exit completely 
from LabView and then re-enter it to create the file! 

I talked to my system person and he said something "like" this. That it 
is a caching problem. Windows has the file in cache memory. All 
references to it affect the cached file. You can do fopens (NULL not 
returned, and errno not set), reads, and writes, but they do not affect 
the file in question on the shared drive. He went on to say thathave to 
use an unbuffered option with "creat" and change all read/writes 
appropriately. 

Will doing a creat with an unbuffered option (his suggestion) help? 

Thank you,
