Member Function Documentation

◆ CalculateTrapHandlerSymbolNames()

void PlatformFreeBSD::CalculateTrapHandlerSymbolNames ( )

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 166 of file PlatformFreeBSD.cpp.

References lldb_private::Platform::m_trap_handlers.

◆ CanDebugProcess()

bool PlatformFreeBSD::CanDebugProcess ( )

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.

◆ GetStatus()

void PlatformFreeBSD::GetStatus ( Stream strm)

Report the current status for this platform.

The returned string usually involves returning the OS version (if available), and any SDK directory that might be being used for local file caching, and if connected a quick blurb about what this platform is connected to.
