Ldr - Loader Manager

There are only a few Ldr routines (36 in Windows 2003 Server). This group includes the following:

• LdrInitializeThunk

• LdrLockLoaderLock

• LdrUnlockLoaderLock

• LdrGetDllHandle

• LdrGetProcedureAddress

If you are hooking loader operations, you will need to look further into the Ldr functional group.
