Classes
struct	viennacl::backend::cpu_ram::detail::array_deleter< U >
	Helper struct for deleting an pointer to an array. More...

Namespaces
	viennacl
	Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them.

	viennacl::backend
	Namespace providing routines for handling the different memory domains.

	viennacl::backend::cpu_ram
	Provides implementations for handling memory buffers in CPU RAM.

	viennacl::backend::cpu_ram::detail
	Holds implementation details for handling memory buffers in CPU RAM. Not intended for direct use by library users.

Typedefs
typedef viennacl::tools::shared_ptr < char >	viennacl::backend::cpu_ram::handle_type

Functions
handle_type	viennacl::backend::cpu_ram::memory_create (vcl_size_t size_in_bytes, const void *host_ptr=NULL)
	Creates an array of the specified size in main RAM. If the second argument is provided, the buffer is initialized with data from that pointer. More...

void	viennacl::backend::cpu_ram::memory_copy (handle_type const &src_buffer, handle_type &dst_buffer, vcl_size_t src_offset, vcl_size_t dst_offset, vcl_size_t bytes_to_copy)
	Copies 'bytes_to_copy' bytes from address 'src_buffer + src_offset' to memory starting at address 'dst_buffer + dst_offset'. More...

void	viennacl::backend::cpu_ram::memory_write (handle_type &dst_buffer, vcl_size_t dst_offset, vcl_size_t bytes_to_copy, const void *ptr, bool)
	Writes data from main RAM identified by 'ptr' to the buffer identified by 'dst_buffer'. More...

void	viennacl::backend::cpu_ram::memory_read (handle_type const &src_buffer, vcl_size_t src_offset, vcl_size_t bytes_to_copy, void *ptr, bool)
	Reads data from a buffer back to main RAM. More...
