Member Function Documentation

◆ Attach()

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

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.

Referenced by DebugProcess().

◆ CalculateTrapHandlerSymbolNames()

void lldb_private::PlatformWindows::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.

Implements lldb_private::Platform.

Definition at line 76 of file PlatformWindows.h.

◆ CanDebugProcess()

bool PlatformWindows::CanDebugProcess ( )
overridevirtual

Not all platforms will support debugging a process by spawning somehow halted for a debugger (specified using the "eLaunchFlagDebug" launch flag) and then attaching.

If your platform doesn't support this, override this function and return false.

Reimplemented from lldb_private::Platform.

lldb_private::Debugger &  debugger,

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.
