~~Title: Efl.Gfx.Buffer.buffer_unmap~~
====== Efl.Gfx.Buffer.buffer_unmap ======


===== Description =====

%%Unmap a region of this buffer, and update the internal data if needed.%%

%%EFL will update the internal image if the map had write access.%%

<note>
%%The %%''slice''%% struct does not need to be the one returned by %%[[:develop:api:efl:gfx:buffer:method:buffer_map|Efl.Gfx.Buffer.buffer_map]]%%, only its contents (%%''mem''%% and %%''len''%%) must match. But after a call to %%[[:develop:api:efl:gfx:buffer:method:buffer_unmap|Efl.Gfx.Buffer.buffer_unmap]]%% the original %%''slice''%% structure is not valid anymore.%%
