call mono_method(pointer) from c

Question

i have mono code

public static unsafe int* mono_method (int* p) { //.... return p; }

and want to call it from native c

MonoObject *result = mono_runtime_invoke(mono_method, NULL, args, NULL);

I tried out some different pointers, variables in the args flag (should be void**)
but always get SIGSEGV error when i execute the runtime invoke.

My question is: Is it possible to pass pointers from c to mono via runtime_invoke and how?

best regards.

You may have tested everything except what the documentation says at http://www.mono-project.com/Embedding_Mono: The params array contains the arguments to the method with the same convention: MonoObject* pointers for object instances and pointers to the value type otherwise.

void* args[1];
int val = 10;
MonoObject *result;
args [0] = &val;
result = mono_runtime_invoke(mono_method, NULL, args, NULL);
/* result will be a boxed IntPtr since pointer types can't be boxed themselves */

Hmm, well then the next question would be, is it possible to pass a pointer to function instead of pointer to int and execute the function in the mono code? — Gobliins, Dec 15 '10 at 08:02
