getChainedFixups

public static List<DyldFixup> getChainedFixups(BinaryReader reader,
 DyldChainedImports chainedImports,
 DyldChainedPtr.DyldChainType pointerFormat,
 long page,
 long nextOff,
 long auth_value_add,

                                        throws IOException,
CancelledException

Walks the chained fixup information and collects a List of DyldFixups that will need to be applied to the image

Parameters:

reader - A BinaryReader that can read the image

chainedImports - chained imports (could be null)

pointerFormat - format of pointers within this chain

page - within data pages that has pointers to be unchained

nextOff - offset within the page that is the chain start

auth_value_add - value to be added to each chain pointer

imagebase - The image base

symbolTable - The SymbolTable, or null if not available

log - The log

monitor - A cancellable monitor

Returns:

A List of DyldFixups

Throws:

IOException - If there was an IO-related issue

CancelledException - If the user cancelled the operation

fixupChainedPointers

                                          throws MemoryAccessException,
CancelledException

Fixes up the program's chained pointers

Parameters:

fixups - A List of the fixups

program - The Program

                                           throws IOException,
CancelledException

Fixes up any chained pointers, starting at the given address.

Parameters:

reader - A BinaryReader that can read the image

chainStart - The starting of address of the pointer chain to fix.

nextOffSize - The size of the next offset.

imagebase - The image base

log - The log

monitor - A cancellable monitor

Returns:
