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
|
||||||
|
========
|
||||||
|
The sokol core headers should not depend on each other, but sometimes
|
||||||
|
it's useful to have a set of helper functions as "glue" between
|
||||||
|
two or more sokol headers.
|
||||||
|
|
||||||
|
This is what sokol_glue.h is for. Simply include the header after other
|
||||||
|
sokol headers (both for the implementation and declaration), and
|
||||||
|
depending on what headers have been included before, sokol_glue.h
|
||||||
|
will make available "glue functions".
|
||||||
|
|
||||||
|
PROVIDED FUNCTIONS
|
||||||
|
==================
|
||||||
|
|
||||||
|
- if sokol_app.h and sokol_gfx.h is included:
|
||||||
|
|
||||||
|
sg_context_desc sapp_sgcontext(void):
|
||||||
|
|
||||||
|
Returns an initialized sg_context_desc function initialized
|
||||||
|
by calling sokol_app.h functions.
