Bug 309

Summary: SDL_Delay() on Mac OS X...
Product: SDL Reporter: Ryan C. Gordon <icculus>
Component: timerAssignee: Ryan C. Gordon <icculus>
Status: RESOLVED INVALID QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: 1.2.11   
Hardware: PowerPC   
OS: Mac OS X (All)   

Description Ryan C. Gordon 2006-08-26 13:19:18 UTC 
The current Mac code for SDL_Delay() yields the CPU to other processes in a loop until the requisite ticks have passed. It appears that OS X either takes this as advisory and doesn't yield if there isn't something explicitly waiting for the CPU, or these system APIs have become no-ops for binary compatibility in Carbon.

We should ifdef these to only be used on OS 9, and have Mac OS X use the POSIX versions, which will put the process to sleep for X ticks.

Comment 1 Ryan C. Gordon 2006-08-27 16:17:23 UTC 
Invalid: Mac OS X uses the POSIX codepath, not the "macos" one, which is for OS 9.
