value

clGetSamplerInfo : procedure?

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

procedure

(clGetSamplerInfo:length sampler    
  param_name) → _size_t/c
  sampler : _cl_sampler/c
  param_name : _cl_sampler_info/c
Returns the size of param_name field of the argument(s). Calls clGetSamplerInfo with values for param_value_size and param_value such that param_value_size_ret is queried.

procedure

(clGetSamplerInfo:_cl_uint sampler    
  param_name) → _cl_uint/c
  sampler : _cl_sampler/c
  param_name : _cl_sampler_info/c
Returns the value associated with param_name for the argument(s). Implemented by clGetSamplerInfo with param_value_size set to (ctype-sizeof _cl_uint) so that the value is queried. Valid param_names are '(CL_SAMPLER_REFERENCE_COUNT).

procedure

(clGetSamplerInfo:_cl_context sampler    
  param_name) → _cl_context/c
  sampler : _cl_sampler/c
  param_name : _cl_sampler_info/c
Returns the value associated with param_name for the argument(s). Implemented by clGetSamplerInfo with param_value_size set to (ctype-sizeof _cl_context) so that the value is queried. Valid param_names are '(CL_SAMPLER_CONTEXT).

procedure

(clGetSamplerInfo:_cl_addressing_mode sampler 
  param_name) 
 → _cl_addressing_mode/c
  sampler : _cl_sampler/c
  param_name : _cl_sampler_info/c
Returns the value associated with param_name for the argument(s). Implemented by clGetSamplerInfo with param_value_size set to (ctype-sizeof _cl_addressing_mode) so that the value is queried. Valid param_names are '(CL_SAMPLER_ADDRESSING_MODE).

procedure

(clGetSamplerInfo:_cl_filter_mode sampler 
  param_name) 
 → _cl_filter_mode/c
  sampler : _cl_sampler/c
  param_name : _cl_sampler_info/c
Returns the value associated with param_name for the argument(s). Implemented by clGetSamplerInfo with param_value_size set to (ctype-sizeof _cl_filter_mode) so that the value is queried. Valid param_names are '(CL_SAMPLER_FILTER_MODE).

procedure

(clGetSamplerInfo:_cl_bool sampler    
  param_name) → _cl_bool/c
  sampler : _cl_sampler/c
  param_name : _cl_sampler_info/c
Returns the value associated with param_name for the argument(s). Implemented by clGetSamplerInfo with param_value_size set to (ctype-sizeof _cl_bool) so that the value is queried. Valid param_names are '(CL_SAMPLER_NORMALIZED_COORDS).

value

clGetSamplerInfo/c : contract?

A contract for the return values of clGetSamplerInfo:generic. Its definition is: (or/c _cl_uint/c _cl_context/c _cl_addressing_mode/c _cl_filter_mode/c _cl_bool/c).

procedure

(clGetSamplerInfo:generic sampler    
  param_name) → clGetSamplerInfo/c
  sampler : _cl_sampler/c
  param_name : _cl_sampler_info/c
Returns the value associated with param_name for the argument(s). Selects the appropriate clGetSamplerInfo-based function to extract the appropriate value, automatically providing the right length for variable length functions.
