◆ Attach()

lldb::ProcessSP lldb_private::PlatformQemuUser::Attach	(	ProcessAttachInfo &	attach_info,
		Debugger &	debugger,
		Target *	target,
		Status &	error
	)

inlineoverridevirtual

Attach to an existing process using a process ID.

Each platform subclass needs to implement this function and attempt to attach to the process with the process ID of pid. The platform subclass should return an appropriate ProcessSP subclass that is attached to the process, or an empty shared pointer with an appropriate error.

Returns: An appropriate ProcessSP containing a valid shared pointer to the default Process subclass for the platform that is attached to the process, or an empty shared pointer with an appropriate error fill into the error object.

Implements lldb_private::Platform.

Definition at line 42 of file PlatformQemuUser.h.

References lldb_private::Status::FromErrorString().

◆ CalculateTrapHandlerSymbolNames()

void lldb_private::PlatformQemuUser::CalculateTrapHandlerSymbolNames ( )

inlineoverridevirtual

Ask the Platform subclass to fill in the list of trap handler names.

For most Unix user process environments, this will be a single function name, _sigtramp. More specialized environments may have additional handler names. The unwinder code needs to know when a trap handler is on the stack because the unwind rules for the frame that caused the trap are different.

The base class Platform ivar m_trap_handlers should be updated by the Platform subclass when this method is called. If there are no predefined trap handlers, this method may be a no-op.

◆ DebugProcess()

lldb::ProcessSP PlatformQemuUser::DebugProcess	(	ProcessLaunchInfo &	launch_info,
		Debugger &	debugger,
		Target &	target,
		Status &	error
	)

overridevirtual

Subclasses do not need to implement this function as it uses the Platform::LaunchProcess() followed by Platform::Attach ().

Remote platforms will want to subclass this function in order to be able to intercept STDIO and possibly launch a separate process that will debug the debuggee.

Reimplemented from lldb_private::Platform.

Definition at line 160 of file PlatformQemuUser.cpp.

◆ FindProcesses()

uint32_t lldb_private::PlatformQemuUser::FindProcesses	(	const ProcessInstanceInfoMatch &	match_info,
		ProcessInstanceInfoList &	proc_infos
	)

inlineoverridevirtual

Attach to an existing process by process name.

This function is not meant to be overridden by Process subclasses. It will first call Process::WillAttach (const char *) and if that returns true, Process::DoAttach (const char *) will be called to actually do the attach. If DoAttach returns true, then Process::DidAttach() will be called.

Parameters

[in] process_name A process name to match against the current process list.

Returns: Returns pid if attaching was successful, or LLDB_INVALID_PROCESS_ID if attaching fails.
