Created page with ''''function''' allocateSharedMemory(''size'') Creates a shared memory object of the given size if it doesn't exist yet. If size is not given and there is no shared region with t…'

New page

'''function''' allocateSharedMemory(''size'')

Creates a shared memory object of the given size if it doesn't exist yet. If size is not given and there is no shared region with this name then the default size of 4096 is used

It then maps this shared memory block into the currently targeted process. It returns the address of mapped region in the target process

When the process closes, you can target another process and allocate the same block on there again. Then you can read the state before the process closed

 '''function''' allocateSharedMemory(''size'')
-Returns the commonModuleList [[StringList]] object.
+Creates a shared memory object of the given size if it doesn't exist yet. If size is not given and there is no shared region with this name then the default size of 4096 is used
-This stringlist object contains a list of modules commonly used in games but not very useful for dissection and pointerscan paths
+It then maps this shared memory block into the currently targeted process. It returns the address of mapped region in the target process
-Tools like dissect data and the pointerscan make use of this list
+When the process closes, you can target another process and allocate the same block on there again. Then you can read the state before the process closed
