1.2.1 Querying Platform Info
| (require opencl/c/4-1) | package: opencl |
procedure
(clGetPlatformIDs:count) → _cl_uint/c
Returns how many results clGetPlatformIDs may return for these arguments.
procedure
(clGetPlatformIDs how-many)
→
_cl_platform_id_vector/c _cl_uint/c how-many : _cl_uint/c
Returns the minimum of how-many and how-many-possible values in rets.
procedure
Returns all possible results from clGetPlatformIDs using clGetPlatformIDs:count to extract the number available.
value
A dummy Racket function that refers callers to the other clGetPlatformInfo-based functions which access the true C function.
procedure
(clGetPlatformInfo:length platform param_name) → _size_t/c platform : _cl_platform_id/null/c param_name : _cl_platform_info/c
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.
procedure
(clGetPlatformInfo:_char* platform param_name param_value_size) → bytes? platform : _cl_platform_id/null/c param_name : _cl_platform_info/c param_value_size : _size_t/c
Returns the value associated with param_name for the argument(s). Implemented by clGetPlatformInfo with param_value_size passed explicitly. Valid param_names are '(CL_PLATFORM_PROFILE CL_PLATFORM_VERSION CL_PLATFORM_NAME CL_PLATFORM_VENDOR CL_PLATFORM_EXTENSIONS).
value
procedure
(clGetPlatformInfo:generic platform param_name) → clGetPlatformInfo/c platform : _cl_platform_id/null/c param_name : _cl_platform_info/c
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.
