sokol_glue.h -- glue helper functions for sokol headers
Project URL: https://github.com/floooh/sokol
Do this:
#define SOKOL_IMPL or
#define SOKOL_GLUE_IMPL
before you include this file in *one* C or C++ file to create the
implementation.
...optionally provide the following macros to override defaults:
SOKOL_ASSERT(c) - your own assert macro (default: assert(c))
SOKOL_GLUE_API_DECL - public function declaration prefix (default: extern)
SOKOL_API_DECL - same as SOKOL_GLUE_API_DECL
SOKOL_API_IMPL - public function implementation prefix (default: -)
If sokol_glue.h is compiled as a DLL, define the following before
including the declaration or implementation:
SOKOL_DLL
On Windows, SOKOL_DLL will define SOKOL_GLUE_API_DECL as __declspec(dllexport)
or __declspec(dllimport) as needed.
OVERVIEW
========
sokol_glue.h provides glue helper functions between sokol_gfx.h and sokol_app.h,
so that sokol_gfx.h doesn't need to depend on sokol_app.h but can be
used with different window system glue libraries.
PROVIDED FUNCTIONS
==================
sg_environment sglue_environment(void)
Returns an sg_environment struct initialized by calling sokol_app.h
functions. Use this in the sg_setup() call like this:
sg_setup(&(sg_desc){
.environment = sglue_environment(),
...
});
sg_swapchain sglue_swapchain(void)
Returns an sg_swapchain struct initialized by calling sokol_app.h
functions. Use this in sg_begin_pass() for a 'swapchain pass' like
this:
sg_begin_pass(&(sg_pass){ .swapchain = sglue_swapchain(), ... });
