From 3b88476130aa2fe1af7d089cd18a9abc72e23678 Mon Sep 17 00:00:00 2001 From: Ruslan Mustakov Date: Wed, 19 Jul 2017 18:49:19 +0700 Subject: Add a way to retrieve stack bottom of the main thread I'm working on Nim bindings and Nim GC needs to know the stack boundaries to check whether certain pointers are located on the stack or in the heap. This commit adds godot_get_stack_bottom procedure to gdnative module which returns pointer to the stack bottom of the main thread. Later on this may be improved to return stack bottom of the current thread. --- modules/gdnative/godot/gdnative.cpp | 5 +++++ modules/gdnative/godot/gdnative.h | 4 ++++ 2 files changed, 9 insertions(+) (limited to 'modules/gdnative/godot') diff --git a/modules/gdnative/godot/gdnative.cpp b/modules/gdnative/godot/gdnative.cpp index 7b94b75a52..29b499ebab 100644 --- a/modules/gdnative/godot/gdnative.cpp +++ b/modules/gdnative/godot/gdnative.cpp @@ -33,6 +33,7 @@ #include "error_macros.h" #include "gdnative.h" #include "global_constants.h" +#include "os/os.h" #include "project_settings.h" #include "variant.h" @@ -89,6 +90,10 @@ godot_object GDAPI *godot_global_get_singleton(char *p_name) { return (godot_object *)ProjectSettings::get_singleton()->get_singleton_object(String(p_name)); } // result shouldn't be freed +void GDAPI *godot_get_stack_bottom() { + return OS::get_singleton()->get_stack_bottom(); +} + // MethodBind API godot_method_bind GDAPI *godot_method_bind_get_method(const char *p_classname, const char *p_methodname) { diff --git a/modules/gdnative/godot/gdnative.h b/modules/gdnative/godot/gdnative.h index 4b79706b52..510bf36cd4 100644 --- a/modules/gdnative/godot/gdnative.h +++ b/modules/gdnative/godot/gdnative.h @@ -245,6 +245,10 @@ void GDAPI godot_object_destroy(godot_object *p_o); godot_object GDAPI *godot_global_get_singleton(char *p_name); // result shouldn't be freed +////// OS API + +void GDAPI *godot_get_stack_bottom(); // returns stack bottom of the main thread + ////// MethodBind API typedef struct { -- cgit v1.2.3
