The caller should pass + arrays sized according to the num_planes values retrieved previously. + Passing arrays of the wrong size will have undefined results. + If the number of fds is less than the number of planes, then + subsequent fd slots should contain -1. + + EGLBoolean eglExportDMABUFImageMESA(EGLDisplay dpy, + EGLImageKHR image, + int *fds, + EGLint *strides, + EGLint *offsets); + + <fds>, <strides>, <offsets> can be NULL if the infomatation isn't + required by the caller. + +Issues + +1. Should the API look more like an attribute getting API? + +ANSWER: No, from a user interface pov, having to iterate across calling +the API up to 12 times using attribs seems like the wrong solution. + +2. Should the API take a plane and just get the fd/stride/offset for that + plane? + +ANSWER: UNKNOWN,this might be just as valid an API. + +3. Does ownership of the file descriptor remain with the app? + +ANSWER: Yes, the app is responsible for closing any fds retrieved. + +4.
