[OSRS-PROJ] Exported function documentation

[Paul Selormey]

Hello All,
Where can I find a complete documentation of the following exported function
from the proj.dll?

pj_init
pj_fwd
pj_inv
pj_free
pj_transform
pj_geocentric_to_geodetic
pj_geodetic_to_geocentric
pj_deallocate_grids
pj_init_plus
pj_latlong_from_proj
pj_is_latlong
pj_get_errno_ref
pj_set_finder
pj_strerrno
pj_errno

If not, can anyone share his/her understanding on any of them? and if
possible
with sample codes? or even test programs?
I have now started using the proj4. I have constructed Visual C++ for the
main
dll, applications (*.exe) and simple testing programs.
I hope to provide a simple COM wrapper for the above exported functions, to
be
used in VB and other projects.

Also, trying to design a control which will serve as some form of
user-interface to
the EPSG file.
Please let me know some of the things you wish to be done. I do not have the
technical
knowledge yet to fix bugs in the algorithm :-) However, I will try to make
it easier to use
for the Windows programmer and I also make it ready for my own programs.

Finally, I will be looking into how the proposed OpenGIS coordinate
transformation COM
interfaces can be exposed by the proj4, and how we could pull all into the
.NET platform,
stay tuned!

Currently, working with the version 4.5.5. Any input will be highly
appreciated. Unfortunately,
this is mainly for the Windows programmer.

To the Windows programmers, do you really use the utility programs like the
Nad2Nad.exe?
Will you prefer a COM interface instead. Please let me know you needs :-)

Please post any large file you wish to share directly to me in order not to
choke others
mails. I will be posting the results to the sister mailing lists at
Yahoogroups.com (such as
the GDAL-DEV), which support file section.

Best regards,
Paul.
