Easy SHM library for C++, still a work in progress but it's a easier way to code up an anonymous SHM mapping, protect the last page and generate a key to access it....I've used similar code quite a bit and was tired of re-coding it. If I find time I'll make it a bit more advanced, like adding a monitor process to cleanup if for some reason the code crashes (you know, things happen right?). I've tested the code on OS X and Linux, but as usual your mileage may vary greatly.
So I've checked the functions found in the testsuite. I've used the code quite a bit in various forms so it should work rather well...however if you find bugs please submit a pull request and I'll get it fixed ASAP.
To build this library on OS X you'll need to run:
mkdir build
cd build
cmake ../build -G<build system of your choice> -DCMAKE_BUILD_TYPE=Release
[make | ninja]
[make | ninja] test- Just run
[make | ninja] install
To use this library, simply:
#include <shm>When compiling your code that uses it, link with -lshm. On Linux you'll have to compile with the -lrt, -lpthread and -lnuma in order to fully utilize all the features. In the future I might add a flag to compile without the NUMA features so that you can use the library without having to install libnuma.
