src/c/gl_native_loader.h — sigil-graphics

1/*

2 * gl_native_loader.h - GL types, constants and entry points for sokol_gfx

3 * without a system GL header or a libGL link.

4 *

5 * GENERATED by scripts/gen-gl-loader.sh from vendor/sokol/sokol_gfx.h

6 * (sokol's own Win32 loader block); do not edit, regenerate after a sokol

7 * bump. Included once, by sokol-graphics.c, ahead of sokol_gfx.h with

8 * SOKOL_EXTERNAL_GL_LOADER defined. Every gl* sokol_gfx calls is a static

9 * function pointer here, filled by sigil_gl_load() through a proc loader

10 * (sigil_desktop_gl_get_proc_address, GLFW's glfwGetProcAddress) once the

11 * window's GL context is current. 122 functions, 249 lines of definitions.
