From 68fef184390da2fd67acfd99fba0a2dbe4a3b875 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Thu, 4 Feb 2010 16:15:45 -0800 Subject: [PATCH] glx: Fix interval test in glXSwapIntervalMESA It appears that, in spite of what the spec says, the interval parameter to glXSwapIntervalMESA has been an unsigned int since day-1. This made the 'if (interval < 0)' test useless. The test is removed and the spec is updated to note that the interval is an unsigned value. --- docs/MESA_swap_control.spec | 7 ++----- src/glx/glxcmds.c | 4 ---- 2 files changed, 2 insertions(+), 9 deletions(-) diff --git a/docs/MESA_swap_control.spec b/docs/MESA_swap_control.spec index ecc674649e2..856978b535b 100644 --- a/docs/MESA_swap_control.spec +++ b/docs/MESA_swap_control.spec @@ -43,7 +43,7 @@ Issues New Procedures and Functions - int glXSwapIntervalMESA(int interval) + int glXSwapIntervalMESA(unsigned int interval) int glXGetSwapIntervalMESA(void) New Tokens @@ -103,11 +103,8 @@ Additions to the GLX 1.3 Specification Errors - glXSwapIntervalMESA returns GLX_BAD_VALUE if parameter is - less than zero. - glXSwapIntervalMESA returns GLX_BAD_CONTEXT if there is no current - GLXContext. + GLXContext or if the current context is not a direct rendering context.
