Hello, I am wondering how to test the number of open
files within a process.  Is there an appropriate system
call?  Also, is there a similar apparatus for testing
the maximum allowable?  Is this maximum configurable
at run time or at compile time (or is something that is
set when the kernel of the OS is built)?  Also, is there
a difference between sockets, streams (FILE*), and regular
file descriptors, or do they all go into the same pool
of available descriptors?

Through debugging, I seem to have figured out the current 
max is 64 within my environment.  (fopen fails at this
point).

I am using currently SunOs 4.1.3, and am using the
gcc (g++).  But I am interested in general info, of
course, as I will expect to be porting to other platforms.

Jason
