"""
Contains a list of EGL functions to generate dispatch functions for.
This is used from gen_egl_dispatch.py.
EGL_FUNCTIONS is a sequence of (name, eglData) pairs, where name is the name
of the function, and eglData is a dictionary containing data about that
function.
The values in the eglData dictionary are:
- method (string):
How to select a vendor library. See "Method values" below.
- prefix (string):
This string is prepended to the name of the dispatch function. If
unspecified, the default is "" (an empty string).
- static (boolean)
If True, this function should be declared static.
- "public" (boolean)
If True, the function should be exported from the library. Vendor libraries
generally should not use this.
- extension (string):
If specified, this is the name of a macro to check for before defining a
function. Used for checking for extension macros and such.
- retval (string):
If specified, this is a C expression with the default value to return if we
can't find a function to call. By default, it will try to guess from the
return type: EGL_NO_whatever for the various handle types, NULL for
pointers, and zero for everything else.
method values:
- "custom"
The dispatch stub will be hand-written instead of generated.
- "none"
No dispatch function exists at all, but the function should still have an
entry in the index array. This is for other functions that a stub may need
to call that are implemented in libEGL itself.
- "display"
Select a vendor from an EGLDisplay argument.
- "device"
Select a vendor from an EGLDeviceEXT argument.
- "current"
Select the vendor that owns the current context.
