3092 :: casting address of pointer functions to a type

• Kerp (orginal) [2017-08-06T07:26:09+02:00] view original

  Hi again just need to know what i'm doing wrong on this subject

  But first here is my code

  
    var vkCreateDebugReportCallbackEXT = cast[PFN_vkCreateDebugReportCallbackEXT](vkGetInstanceProcAddr(inst,"vkCreateDebugReportCallbackExt"))
  
  Run

  i get a message from the compiler about this when i try it, that it cannot convert to a pointer type. i believe its because its pointer function in c and maybe nim does not like casting those, i dunno?

  Your type PFN_vkCreateDebugReportCallbackEXT must have a calling convention like stdcall or cdecl for this to work. The default is closure which is actually a (fn, env) pair.
