(clCreateSampler		ctxt

ctxt : _cl_context/c

normalized? : _cl_bool/c

addressing-mode : _cl_addressing_mode/c

filter-mode : _cl_filter_mode/c

(clRetainSampler sampler) → void

sampler : _cl_sampler/c

sampler : _cl_sampler/c

clGetSamplerInfo : procedure?

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

(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.

(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).

(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).

(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).

(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).

(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).

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).

(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.
