clCreateSampler - Creates a sampler object.
cl_sampler clCreateSampler(cl_context context, cl_bool normalized_coords, cl_addressing_mode addressing_mode, cl_filter_mode filter_mode, cl_int *errcode_ret);
A sampler object describes how to sample an image when the image is read in the kernel. The built-in functions to read from an image in a kernel take a sampler as an argument. The sampler arguments to the image read function can be sampler objects created using OpenCL functions and passed as argument values to the kernel or can be samplers declared inside a kernel. In this section we discuss how sampler objects are created using OpenCL functions.
For more information about working with samplers, see sampler_t(3clc)
Returns a valid non-zero sampler object and errcode_ret is set to CL_SUCCESS if the sampler object is created successfully. Otherwise, it returns a NULL value with one of the following error values returned in errcode_ret:
clRetainSampler(3clc), clReleaseSampler(3clc), clGetSamplerInfo(3clc), classDiagram(3clc) sampler_t(3clc)
