Detailed Description

Portable process status.

Definition at line 122 of file Process.hpp.

Constructor & Destructor Documentation

Status() [1/3]

BLOCXX_NAMESPACE::Process::Status::Status	(	ProcId	wpid,
		int	status )

Invariant

Exactly one of running(), stopped() and terminated() is true.

Parameters

wpid	return value from waitpid
status	status value assigned by waitpid.

Definition at line 102 of file Process.cpp.

Status() [2/3]

BLOCXX_NAMESPACE::Process::Status::Status	(	int	rep1,
		int	rep2,
		Repr	)

Precondition

rep1 and @rep2 were obtained by a prior call to repr() on some Status object.

Definition at line 108 of file Process.cpp.

Status() [3/3]

BLOCXX_NAMESPACE::Process::Status::Status

(

)

Postcondition

running() is true
