[section:IoObjectService I/O object service requirements]
|
|
|
|
An I/O object service must meet the requirements for a [link
|
|
boost_asio.reference.Service service], as well as the requirements listed
|
|
below.
|
|
|
|
In the table below, `X` denotes an I/O object service class, `a` and `ao` denote
|
|
values of type `X`, `b` and `c` denote values of type `X::implementation_type`,
|
|
and `u` denotes an identifier.
