Module: Syscalls

Defined in:

lib/syscalls.rb,
lib/syscalls/version.rb

Overview

System call constants (e.g. SYS_open).

The constant names and values in this module are system-dependent. They are read in from sys/syscall.h when this gem is built.

The SYS_NUMBER and SYS_NAME hashes provide an easy way of converting from names to numbers.

A Syscalls.syscall method is also provided; it is identical to Kernel.syscall in 1.9.2-p290, except that it doesn’t give a warning that it will one day be removed.
