It seems to me that a lot of the OpenCL kernel argument setting can be streamlined. The most rudimentary thing one can think of is implementing:
clSetKernelArgs(cl_kernel kernel, unsigned num_args, ...)
and then for each argument can one can read either a triplet of arg_index, arg_size and value, or a pair of arg_size and arg_value, or even just the argument (if one could somehow figure out within the impl what the signature types are).
Isn't this already implemented somewhere as part of the standard?
Note: I'm interested both in C and C++ code.
