Returns how many results clGetPlatformIDs may return for these arguments.

Returns the minimum of how-many and how-many-possible values in rets.

Returns all possible results from clGetPlatformIDs using clGetPlatformIDs:count to extract the number available.

A dummy Scheme function that refers callers to the other clGetPlatformInfo-based functions which access the true C function.

Returns the size of param_name field of the argument(s). Calls clGetPlatformInfo with values for param_value_size and param_value such that param_value_size_ret is queried.

Returns the value associated with param_name for the argument(s). Implemented by clGetPlatformInfo with param_value_size passed explicitly. Uses clGetPlatformInfo:length to find the maximum value. Valid param_names are '(CL_PLATFORM_PROFILE CL_PLATFORM_VERSION CL_PLATFORM_NAME CL_PLATFORM_VENDOR CL_PLATFORM_EXTENSIONS).

A contract for the return values of clGetPlatformInfo:generic. Its definition is: (or/c bytes?).

Returns the value associated with param_name for the argument(s). Selects the appropriate clGetPlatformInfo-based function to extract the appropriate value, automatically providing the right length for variable length functions.
