Function documentation

bpf::system::Process::Process(Process&& other) noexcept

Move constructor

bpf::system::Process::Process(const Process& other) deleted

Force compiler to NEVER ever copy that class

bpf::system::Process::~Process()

Destructor, the process gets automatically killed if this is reached

Process& bpf::system::Process::operator=(const Process& other) deleted

Force compiler to NEVER ever copy that class

Process& bpf::system::Process::operator=(Process&& other) noexcept

Move assignment operator

void bpf::system::Process::Wait()

Exceptions
OSException in case the system can't wait for the process

Wait for the process to terminate

void bpf::system::Process::Kill(bool force)

Parameters
force true to force kill, false otherwise
Exceptions
OSException in case the system could not send signal

Kill the target process

uint32 bpf::system::Process::GetExitCode()

Returns exit code as an integer, undefined if process is still running
Exceptions
OSException in case the system could not poll the target process

Returns the exit code of the process

bool bpf::system::Process::IsRunning() const noexcept

Returns true if the process is running, false otherwise

Checks if this process is still running

bool bpf::system::Process::IsCrashed() const noexcept

Returns true if the process is crashed, false otherwise

Checks if this process is crashed

PipeStream& bpf::system::Process::GetStandardInput()

Returns reference to IOutputStream
Exceptions
OSException if the target process does not allow standard input redirection

Provides access to process standard input

PipeStream& bpf::system::Process::GetStandardOutput()

Returns reference to IInputStream
Exceptions
OSException if the target process does not allow standard output redirection

Provides access to process standard output

PipeStream& bpf::system::Process::GetStandardError()

Returns reference to IInputStream
Exceptions
OSException if the target process does not allow standard error redirection

Provides access to process standard error
