Wed Apr 13 10:25:11 UTC 2016
refactor configuration API of headless-backend
Signed-off-by: Bryce Harrington <bryce at osg.samsung.com>
---
v5:
- update to current trunk
- fixed typo 'struct weston_wayland_backend_config'
- dropped unused variables
- dropped weston_headless_backend_config_create() in favor of
directly zalloc'ing the object
- dropped weston_headless_backend_load() in favor of the more
generalized load_backend_new().
- dropped typedef from header
- restored use of 'backend_init' entry point
- backend_init() takes a base weston_backend_config object
- renamed 'param' to 'config' in a few places for consistency
- renamed 'headless_options' variable to 'options for consistency
- version the base struct
- free config on error
- don't free config during backend_init normal operations
- adjust header ordering
- make header guard naming consistent with other headers
- light reformatting for code style and consistency with other
backend config patches
