◆ CanLoadImage()

Status DynamicLoaderDarwinKernel::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.
