C++ program locked up on function call: fwrite.

Operation System: HP-UX 10.20
Language: C++

I wrote a program which runs all the time to
collect historic data and write data into binary files at a period
of time, the problem is that it randomly hangs up on function call: fwrite,
(Sometime on function call: fread.) Based on hp manual page,
'fwrite' does not do any locking up for no-thread application.
Any idea about that? Thanks.

can you provide more details like a snippet of the code which would be more helpful.

Paddy,
Thanks for your quick reply.
The attachment file (microsoft word) is code segments for the situation.

Any help is highly appreciated.
