Bug 1448

Summary: SDL_PushEvent does not copy event
Product: SDL Reporter: andre
Component: *don't know*Assignee: Ryan C. Gordon <icculus>
Status: RESOLVED INVALID QA Contact: Sam Lantinga <slouken>

Description andre 2012-03-13 15:35:40 UTC 
The docs for SDL_PushEvent state "The event is copied into the queue, and the caller may dispose of the memory pointed to after SDL_PushEvent() returns.".  This is not the case in the current HG codebase.  I am not sure if this is a documentation error, a non-implemented feature, or a bug.  The pointer for the event is copied, and the event itself is not copied.

The event is copied by value. SDL_PushEvent calls SDL_PeepEvent, which calls SDL_AddEvent, which performs the by-value copy.
Comment 2 Sam Lantinga 2013-03-01 01:25:52 UTC 
Note that if your event contains userdata pointers, the pointers are copied, not the memory they point to.  You need to manage those objects yourself and make sure you don't free them while the event is being delivered.
