Member Function Documentation

◆ CanLoadImage()

Status DynamicLoaderWindowsDYLD::CanLoadImage ( )
overridevirtual

Ask if it is ok to try and load or unload an shared library (image).

The dynamic loader often knows when it would be ok to try and load or unload a shared library. This function call allows the dynamic loader plug-ins to check any current dyld state to make sure it is an ok time to load a shared library.

Returns
true if it is currently ok to try and load a shared library into the process, false otherwise.

◆ GetStepThroughTrampolinePlan()

ThreadPlanSP DynamicLoaderWindowsDYLD::GetStepThroughTrampolinePlan ( Thread thread,
bool  stop_others

overridevirtual

Provides a plan to step through the dynamic loader trampoline for the current state of thread.

Parameters
[in]stop_othersWhether the plan should be set to stop other threads.
Returns
A pointer to the plan (caller owned) or NULL if we are not at such a trampoline.
