Checking wether a command queue is valid...
I would like to check if a given comand queue is valid. (I have a lot of host code, some functions taking a command queue as a parameter, and I had a bug where I gave an unitialised command queue, so I would like to avoid such a bug in the future).
Anyway, I have tried a simple:
bool queueValid(const cl_command_queue& queue)
cl_int err = clGetCommandQueueInfo(queue, CL_QUEUE_DEVICE, 0, NULL, &size);
return (err == CL_SUCCESS);
But it turns out that calling clGetCommandQueueInfo on an unitialised queue segfault. (AMD APP SDK 2.7)
I have seen a previous post about "Check whether cl_mem object is valid":http://www.khronos.org/message_board...hp?f=28&t=4995
but it does not seem to apply to queues.
Any pointer ? (no pun intended!)
Thanks a lot in advance.
Re: Checking wether a command queue is valid...
Just write more robust code ...? :)
They're just pointers, so treat them like any other pointer. i.e. init to 0, use !0 checks, and/or fail earlier if they aren't created in the first place.
