main.c is the code for a simple injector tool that will wait for a running javaw.exe process, and then inject VoxelMapRedirDLL.dll into it.

dllmain.c is the code for an injected DLL that fixes an old version of the Minecraft mod VoxelMap. It allows the mod to work when connecting to realms. It hooks CreateFileW and GetFileAttributesExW looking for filenames with specific path elements, and will rewrite them to utilize a file containing the string "realms" in place of an IP address, which the realm system does not expose.
It requires linking in a multi-threaded version of libMinHook and requires the associated MinHook.h file.
