Calling a DLL from GNAT

Calling a DLL from GNAT

[markp]

I am going to be provided a DLL of C functions that I need to interface
with in GNAT. I know how to call C functions from Ada. However, I'm not
sure how to link the DLL in with the Ada source code under the GPS
environment. Could anyone assist in this?

Thank you.

That GNAT documentation describes this pretty well.

http://gcc.gnu.org/onlinedocs/gnat_ugn_unw/Using-DLLs-with-GNAT.html#Using-DLLs-with-GNAT


Perhaps you can come back with specific questions.

If you are using .gpr files and a farly new GNAT then it may be possible 
to do it this way

project externallib is
   for Source_Dirs use ();
   for Library_Dir use "relative path to dll from project file"
   for Library_Name use "what ever the basename of the dll is";
   for library_kind use "dynamic";
end externallib;

with "externallib";
project the_proj is

end the_proj;


It is all well described in
"http://gcc.gnu.org/onlinedocs/gnat_ugn_unw/Stand_002dalone-Library-Projects.html#Stand_002dalone-Library-Projects"
the GNAT users guide covering library projects.
