Hi Ed,

Looks like most of the function implementations are in
OOps/pvfileio.c.  The source for pvanal is in the util folder.  I
haven't looked at that code so can't comment further! :)

Cheers!

You can use nm, pexports, dumpbin, or some similar utility to
determine if, and where, these functions are exported (i.e., made
available to be linked with by some external software).

If so, then you can declare the types of these functions as 'extern'
in your code, e.g. 'extern int myfunct(const char* mystring, double
mydouble);' You don't actually need a header file, a header file just
make this procedure safer and more convenient.

You can then call these functions in your code. Of course you will
need to link with the object file, static library, or shared library
that actually defines these functions.

Regards,
Mike
