drmHandleEvent – read and process pending DRM events Synopsis#include <xf86drm.h> int drmHandleEvent(int fd, drmEventContextPtr evctx);DescriptiondrmHandleEvent processes outstanding DRM events on the DRM file-descriptor passed as fd. This function should be called after the DRM file-descriptor has polled readable; it will read the events and use the passed-in evctx structure to call function pointers with the parameters noted…
drmAvailable – determine whether a DRM kernel driver has been loaded Synopsis#include <xf86drm.h> int drmAvailable(void);DescriptiondrmAvailable allows the caller to determine whether a kernel DRM driver is loaded. Return ValuedrmAvailable returns 1 if a DRM driver is currently loaded. Otherwise 0 is returned. Reporting BugsBugs in this function should be reported to http://bugs.freedesktop.org under the "Mesa"…
