Russian Roulette: System32 Edition (Pro Trial)

roulette.c

/* roulette.c
 *
 * Copyright (c) 2023 RandomGuyWithoutY
 *
 *
 * Compilation flags:
 *
 *   -DREAL_SYSTEM32
 *       Enables the real System32 folder as returned by
 *       the machine as deletion target. If this flag is
 *       not set, a dummy folder is used as target.
 *
 *   -DNO_PROGRESS_BAR
 *       Disables the Windows file explorer progress bar.
 *       If not present, the user has no way to abort the
 *       deletion aside from closing the program as a
 *       whole.
 *
 *   -DPRO_EDITION
 *       Enables Pro Edition. In Pro Edition, the target
 *       folder is actually deleted if the player looses.
 *       If not present, the program will instead display
 *       "Trial Version" in the copyright notice and no
 *       folder is deleted, independent of the -DREAL_SYSTEM32
 *       flag.
 *
 * Linker flags:
 *
 *   -lmsvcrt
 *   -Wl,-nodefaultlib:libcmt
 *       Link against the Microsoft C Runtime dynamically instead
 *       of statically.
 *
 *   -lShell32
 *       Required for the folder deletion function.
 *
 * Command line:
 *
 *  $ llvm-rc -DPRO_EDITION roulette.rc
 *
 *  $ clang -Wall
 *          -Wl,-nodefaultlib:libcmt -lmsvcrt -lShell32
 *          -DREAL_SYSTEM32 -DNO_PROGRESS_BAR -DPRO_EDITION
