unbound/dynlibmod/examples/helloworld.c

/*
 * This is an example to show how dynamic libraries can be made to work with
 * unbound. To build a .so file simply run:
 *   gcc -I../.. -shared -Wall -Werror -fpic  -o helloworld.so helloworld.c
 * And to build for windows, first make unbound with the --with-dynlibmod
 * switch, then use this command:
 *   x86_64-w64-mingw32-gcc -m64 -I../.. -shared -Wall -Werror -fpic -o helloworld.dll helloworld.c -L../.. -l:libunbound.a
 * to cross-compile a 64-bit Windows DLL.
