[Mono-dev] Error handling for embedded Mono

[luke at quinane.id.au]

Hi All,

I was looking at embedding Mono into a project and noticed that in several
places Mono simply calls exit(-1) when it has a problem. This is obviously
not a very good solution for a project that is running embedded Mono; a
nicer solution would be to return an error code that could be handled by
the host program.

I had a look at making some changes to remove some of these calls but ran
into some problems. For example mono_init_internal calls exit (line 586 of
domain.c) but by that point the domain has been allocated and a lot of
things have been initialized. So my question is how does Mono handle such
errors? Is it possible to return NULL for the domain and just call
mono_jit_cleanup?

Also should mono_runtime_run_main (in object.c) set
mono_environment_exitcode_set and return -1 instead of calling exit?


Cheers,

Luke
