Very Computer

 Hi,

 Can I set up one file in order to have only one fd ?

 I want to do that only one process can read it.

 Thanks in advance

unlink (delete) the 'file' after openning it.

Cheers,

You can use locking for exclusive access.

This would work only if you had either mandatory locking on the file
or a restricted set of programs which would respect the advisory locks.
N.b. Not all OSes support mandatory locks; Linux 1.2.x is one example.
