Instance Method Details

#create_sub_buffer(type, region, options = {}) ⇒ Object

Creates a Buffer from a sub part of the Buffer

Attributes

  • info - inf reguarding the type of sub-buffer created. if type == OpenCL::BUFFER_CREATE_TYPE_REGION, info is a BufferRegion

  • tyep - type of sub-buffer to create. Only OpenCL::BUFFER_CREATE_TYPE_REGION is supported for now

  • options - a hash containing named options

Options

  • :flags - a single or an Array of :cl_mem_flags specifying the flags to be used when creating the Buffer
