POSIX Semaphores

What

Linux now provides a complete implementation of POSIX semaphores.

When

Linux 2.6.0, glibc 2.3.

Where

Standardized as an option in SUSv3.

Why

POSIX semaphores provide a nicer API than System V semaphores:

• API is simpler (we'll skip the details).
  
  
• Initialization is easier.
  
  

But slightly less portable.
