That confirms my suspicions.

It is a porting library, containing the wrapper routines for building 
SAMBA 2.0.6 using almost completely unmodified UNIX source.  Most of the 
modifications in SAMBA 2.0.6 were bug fixes that were not OpenVMS specific.

Features unique to Frontport that are not in the other porting libraries 
  are:

It implements fcntl() using RMS locking, so that programs using it will 
honor RMS locks in other programs, and other programs will honor locks 
on it.

It implements the crypt() function that returns an OpenVMS password 
Hash, when used with the getpwnam() call.

The SETUID() code is automatically linked when the image is installed if 
  needed.  It is also not required for non-privileged images.


If you have not read my porting notes for Samba 2.0.6 and for FRONTPORT, 
I would recommend it.

Both can be found on the OpenVMS Freeware 5.0 CD-ROM.  An image of the 
CD-ROM set is available from a link at http://www.openvms.com.

decc*.olb is installed with the compiler.  It is redistributable with an 
application provided the conditions in SYS$LIBRARY:DECC$CRTL.README.

It may not work because of image ident mismatches.


The FRONTPORT library was intended to be able to work as far back as 
OpenVMS 5.5-2, however it is restricted to 7.0 and later.

It's purpose was to be used with more applications than just SAMBA.

I am almost to the point where I can start doing work again, and I have 
a number of fixes lined up for Frontport.  One of the things that I want 
to implement is a compliance test suite for it's various features.

Carl Perkins has sent me code that looks like it will solve the OLE 
locking problems, and possibly a few other special cases.

I have also now learned how to get the locking to work with out changing 
the file modification dates.

I expect to be testing it initially against the 2.0.x stream of SAMBA so 
that I can fix some of the problems that I have learned about in the 
2.0.6 version.

I have no timetable for this though, at my new job, I am spending about 
an hour a day commuting that I used to spend coding.

My personal development platforms have been upgraded both in CPU power 
and in storage capacity, so I may be able to track multiple streams.
