Graphics Driver API

This chapter includes reference pages for the entry points your driver must provide, as well as for the macros and data structures you'll use when writing a graphics driver:

devg_get_contextfuncs()

Get a table of your driver's context drawing functions

devg_get_corefuncs()

Get a table of your driver's core 2D drawing functions

devg_get_memfuncs()

Get a table of your driver's video memory-management functions

devg_get_miscfuncs()

Get a table of your driver's miscellaneous drawing functions

devg_get_modefuncs()

Get a table of your driver's modeswitcher functions

devg_get_rendfuncs()

Get a table of your driver's 3D rendering functions
