Detailed Description

Evaluates a subcommand in background semantics (implementation-specific).

The constructor takes ownership of the subcommand to be run in background.

Constructor & Destructor Documentation

shell_node_background()

bs::shell_node_background::shell_node_background	(	std::size_t	nPos,
		std::unique_ptr< shell_node_evaluable > &&	pCommand
	)

Construct a background command node.

Exceptions

shell_node_invalid_argument

If pCommand is null.

Parameters

nPos	Background operator position.
pCommand	Owned evaluable subcommand.

Member Function Documentation

evaluate()

shell_status bs::shell_node_background::evaluate ( shell_session &  oSession ) const

overridevirtual

Evaluate the background node (typically launches and returns immediately).

Parameters

oSession

Session context.

Returns

shell_status Execution result or job control status.

Implements bs::shell_node_evaluable.

get_command()

const shell_node_evaluable * bs::shell_node_background::get_command ( ) const

inlinenoexcept

Get pointer to the underlying command.

Returns

Non-owning pointer to underlying command.
