From 38ba5881a078eb35b3f82abaf5e4873a9a3a981e Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Wed, 2 Jun 2021 17:02:28 +0200 Subject: buffer: replace get_data_ptr with {begin,end}_data_ptr_access This new API allows buffer implementations to know when a user is actively accessing the buffer's underlying storage. This is important for the upcoming client-backed wlr_buffer implementation. --- include/wlr/types/wlr_buffer.h | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'include/wlr') diff --git a/include/wlr/types/wlr_buffer.h b/include/wlr/types/wlr_buffer.h index 3b8b76f6..47f17cce 100644 --- a/include/wlr/types/wlr_buffer.h +++ b/include/wlr/types/wlr_buffer.h @@ -26,10 +26,11 @@ struct wlr_buffer_impl { void (*destroy)(struct wlr_buffer *buffer); bool (*get_dmabuf)(struct wlr_buffer *buffer, struct wlr_dmabuf_attributes *attribs); - bool (*get_data_ptr)(struct wlr_buffer *buffer, void **data, - uint32_t *format, size_t *stride); bool (*get_shm)(struct wlr_buffer *buffer, struct wlr_shm_attributes *attribs); + bool (*begin_data_ptr_access)(struct wlr_buffer *buffer, void **data, + uint32_t *format, size_t *stride); + void (*end_data_ptr_access)(struct wlr_buffer *buffer); }; /** @@ -47,6 +48,7 @@ struct wlr_buffer { bool dropped; size_t n_locks; + bool accessing_data_ptr; struct { struct wl_signal destroy; -- cgit v1.2.3
