libbase — low-level utility library for Windows x64

Native DLL exposing system-level utilities with ability to export.

Stack: FASM

Features

• FastZeroMemory — optimized memory zeroing
• FastSort — fast sort implementation
• Hardware-backed random number generation via RDRAND:
  • Integer types: Random64/32/16/8 with min/max range variants
  • Floating point: RandomDouble, RandomSingle

Note

Range functions may produce invalid results when min/max values are near the type's boundary limits.
