◆ CanLoadImage()

Status DynamicLoaderMacOSXDYLD::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.

	)

overridevirtual

Get information about the shared cache for a process, if possible.

On some systems (e.g. Darwin based systems), a set of libraries that are common to most processes may be put in a single region of memory and mapped into every process, this is called the shared cache, as a performance optimization.

Many targets will not have the concept of a shared cache.

Depending on how the DynamicLoader gathers information about the shared cache, it may be able to only return basic information - like the UUID of the cache - or it may be able to return additional information about the cache.

Parameters

[out]	base_address	The base address (load address) of the shared cache. LLDB_INVALID_ADDRESS if it cannot be determined.
[out]	uuid	The UUID of the shared cache, if it can be determined. If the UUID cannot be fetched, IsValid() will be false.
[out]	using_shared_cache	If this process is using a shared cache. If unknown, eLazyBoolCalculate is returned.
[out]	private_shared_cache	A LazyBool indicating whether this process is using a private shared cache. If this information cannot be fetched, eLazyBoolCalculate.

Returns: Returns false if this DynamicLoader cannot gather information about the shared cache / has no concept of a shared cache.
