epoxy_conservative_glx_version()

If we can determine the GLX version from the current context, then return that, otherwise return a version that will just send us on to dlsym() or get_proc_address().

void* epoxy_egl_dlsym

(

)

epoxy_get_bootstrap_proc_address()

void* epoxy_get_bootstrap_proc_address

(

const char *

name

)

Performs the dlsym() for the core GL 1.0 functions that we use for determining version and extension support for deciding on dlsym versus glXGetProcAddress() for all other functions.

This needs to succeed on implementations without GLX (since glGetString() and glGetIntegerv() are both in GLES1/2 as well, and at call time we don't know for sure what API they're trying to use without inspecting contexts ourselves).

epoxy_get_core_proc_address()

void* epoxy_get_core_proc_address	(	const char *	name,
		int	core_version
	)

Performs either the dlsym or glXGetProcAddress()-equivalent for core functions in desktop GL.

epoxy_gles3_dlsym()

void* epoxy_gles3_dlsym

(

const char *

name

)

Does the appropriate dlsym() or eglGetProcAddress() for GLES3 functions.

Mesa interpreted GLES as intending that the GLES3 functions were available only through eglGetProcAddress() and not dlsym(), while ARM's Mali drivers interpreted GLES as intending that GLES3 functions were available only through dlsym() and not eglGetProcAddress(). Thanks, Khronos.
