[cffi-devel] Passing a struct by value
by Luke Crook 07 Jun '06

07 Jun '06

I've read: http://article.gmane.org/gmane.lisp.cffi.devel/754 stating that CFFI does not support passing structs by value. Unfortunately I need to pass a SDL_Color struct *by value* to the SDL_ttf library in order to set the character/font color prior to rendering. I'll need to write some 'glue' code in C to do this conversion. Does anyone have any suggestions on the best way I should implement this? A 'wrapper' function in a helper DLL that will take the SDL_Color struct pointer from CFFI and call the SDL_ttf function passing the struct as a value? Thanks, -Luke

FLI's documentation suggests foreign-typed-aref expects array indexes but it seems to want offsets in bytes instead. - Regression tests: mem-ref.rt.1 and mem-ref.rt.2.
