ruby-syscalls
===

An FFI based library which implements some missing POSIX system calls, sticking
very closely to the C counterparts.


Requirements
===

* FFI

Tested on MRI 1.9.1 and 1.8.6.

On MRI < 1.8.7, sigprocmask() is not defined due to a bug in the interpretter.


Example
===

Simple example, no error checks:

C:

  #include <signal.h>

  sigset_t sigset;

  sigemptyset(&sigset);
  sigaddset(&sigset, SIGUSR1);
  sigsuspend(&sigset);


Ruby:

  require "syscalls/signal"
  
  sigset = Syscalls::Sigset_t.new.ptr

  Syscalls.sigemptyset(sigset)
  Syscalls.sigaddset(sigset, "USR1")
  Syscalls.sigsuspend(sigset)
  

Or, shorter:

  require "syscalls/signal"
  
  Syscalls.sigsuspend([ "USR1" ])
