plibsys is a cross-platform system C library with some helpful routines. It has zero third-party dependencies and uses only native system calls.


plibsys gives you:

  • Platform independent data types
  • Threads
  • Mutexes
  • Condition variables
  • Read-write locks
  • System-wide semaphores
  • System-wide shared memory
  • Optimized spinlock
  • Atomic operations
  • Socket support (UDP, TCP, SCTP) with IPv4 and IPv6
  • Hash functions: MD5, SHA-1, SHA-2, SHA-3, GOST (R 34.11-94)
  • Binary trees: BST, red-black, AVL
  • INI file parser
  • High resolution time profiler
  • Files and directories
  • Shared library loading
  • Useful routines for linked lists, strings, hash tables
  • Macros for CPU architecture, OS and compiler detection
  • Macros for variable arguments

To achieve maximum native performance on each platform several implementation models are used:

  • Threading models: POSIX, Solaris, OS/2, BeOS, AtheOS, AmigaOS and Win32
  • IPC models: POSIX, System V, OS/2, AmigaOS and Win32
  • Time profiler models: POSIX, Solaris, Mach, OS/2, BeOS, AmigaOS, Win32 and generic
  • Directory iterating models: POSIX, OS/2 and Win32
  • Shared library loading models: POSIX, HP-UX, OS/2, BeOS, AmigaOS and Win32
  • Atomic operations models: sync, C11, DECC, Win32 and simulated
  • Sockets: BSD with Win32 support


plibsys is a cross-platform, highly portable library, it is fully covered with unit tests and was tested on the following desktop platforms:

  • GNU/Linux
  • macOS
  • Windows
  • Cygwin, MSYS
  • FreeBSD, NetBSD, OpenBSD
  • DragonFlyBSD
  • Solaris
  • AIX
  • HP-UX
  • Tru64
  • OpenVMS
  • OS/2
  • IRIX
  • QNX Neutrino
  • UnixWare 7
  • SCO OpenServer 5
  • Haiku
  • Syllable
  • BeOS
  • AmigaOS

plibsys also supports the following mobile platforms:

  • iOS, watchOS, tvOS
  • Android
  • BlackBerry 10

It should also work on other *nix systems with or without minimal efforts.


plibsys was tested with the following compilers:

  • MSVC (x86, x64) 2003 and above
  • MinGW (x86, x64)
  • Open Watcom (x86)
  • Borland (x86)
  • GCC (x86, x64, PPC32be, PPC64be/le, IA-64/32, IA-64, Alpha, HPPA2.0-32, MIPS32, AArch32, SPARCv9)
  • Clang (x86, x64, PPC32be, AArch32, AArch64)
  • Intel (x86, x64)
  • QCC (x86, AArch32)
  • Oracle Solaris Studio (x86, x64, SPARCv9)
  • MIPSpro (MIPS32)
  • XL C (PPC64le)
  • DEC C (Alpha)
  • PGI (x86, x64)
  • Cray (x64)


Use CMake to build plibsys for target platform. For OpenVMS see platforms/vms-general directory.


Documentation for the latest stable verison is avaialble through the GitHub Pages.
