NAME¶clRetainCommandQueue - Increments the command_queue reference count.
cl_int clRetainCommandQueue(cl_command_queue command_queue);
NOTES¶clCreateCommandQueue(3clc) performs an implicit retain. This is very helpful for 3rd party libraries, which typically get a command-queue passed to them by the application. However, it is possible that the application may delete the command-queue without informing the library. Allowing functions to attach to (i.e. retain) and release a command-queue solves the problem of a command-queue being used by a library no longer being valid.
ERRORS¶Returns CL_SUCCESS if the function executed successfully, or one of the errors below:
SEE ALSO¶clCreateCommandQueue(3clc), clGetCommandQueueInfo(3clc), clReleaseCommandQueue(3clc)
