Detailed Description

Allows retreiving read/write access to read-only kernel memory.

This class allows modifying read-only kernel memory. On x86 targets, all kernel memory is always writable by kernel-mode code, however, on x64 targets, some memory (such as code segments) is marked as read-only. This class allows retreiving a write-enabled pointer to a read-only memory block.
