Calling D function from C

[Sivo Schilling]

Reply to Jonathan:

I investigated this problem some days ago to find a way for such
callbacks from C code to D code. See the attached files cexception.c
and dexception.d. 
Build the executable (Windows & DMD 1.028 or DMD 2.012 & DM 8.50) 
via

sc -c cexcexption.c
dmd -c dexception.d
link cexcexption.obj+dexcexption.obj, dcexception.exe

Good luck
Sivo.
