Installation

Add the following line to your deps in mix.exs. Run mix deps.get.

    {:shmex, "~> 0.5.0"}

All native stuff is exported in :lib and :shmexBundlex dependencies. To import, add the following line to your nif specification in bundlex.exs

deps: [shmex: :lib]

and another one in your native header file

#import <shmex/lib.h>

To execute tests run mix test. These test tags are excluded by default:

shm_tmpfs - tests that require access to information about shared memory segments present in the OS via tmpfs, not supported e.g. by Mac OS
shm_resizable - tests for functions that involve resizing existing shared memory segments, not supported e.g. by Mac OS
