NAME

       clCreateUserEvent - Creates a user event object.

       cl_event clCreateUserEvent(cl_context context, cl_int *errcode_ret);

PARAMETERS

       context
           A valid OpenCL context used to create the user event object.

       errcode_ret
           Returns an appropriate error code. If errcode_ret is NULL, no error code is returned.

NOTES

       User events allow applications to enqueue commands that wait on a user event to finish before the command
       is executed by the device.

       The execution status of the user event object created is set to CL_SUBMITTED.

ERRORS

       Returns a valid non-zero buffer object and errcode_ret is set to CL_SUCCESS if the user event object is
       created successfully. Otherwise, it returns a NULL value with one of the following error values returned
       in errcode_ret:

       •   CL_INVALID_CONTEXT if context is not a valid context.

       •   CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation
           on the device.

       •   CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL
           implementation on the host.
