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(), ... });
