Member Typedef Documentation

typedef asio::detail::io_control::bytes_readable asio::posix::descriptor_base::bytes_readable

IO control command to get the amount of data that can be read without blocking. Implements the FIONREAD IO control command.

Example

 asio::posix::stream_descriptor descriptor(io_service); 
 ...
 asio::descriptor_base::bytes_readable command(true);
 descriptor.io_control(command);
 std::size_t bytes_readable = command.get();

Concepts:

IoControlCommand.

Definition at line 78 of file descriptor_base.hpp.

typedef asio::detail::io_control::non_blocking_io asio::posix::descriptor_base::non_blocking_io

IO control command to set the blocking mode of the descriptor.

Implements the FIONBIO IO control command.

Example

 asio::posix::stream_descriptor descriptor(io_service); 
 ...
 asio::descriptor_base::non_blocking_io command(true);
 descriptor.io_control(command);

Concepts:

IoControlCommand.
