I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability.
Obviously, I'll have to worry about mutual exclusion. (0 Replies)

I need to create a shared library to access an in memory DB. The DB is not huge, but big enough to make it cumbersome to carry around in every single process using the shared library.

DLCLOSE(3) BSD Library Functions Manual DLCLOSE(3)
NAME
dlclose -- close a dynamic library or bundle
SYNOPSIS
#include <dlfcn.h>
int
dlclose(void* handle);
DESCRIPTION
dlclose() releases a reference to the dynamic library or bundle referenced by handle. If the reference count drops to 0, the bundle is
removed from the address space, and handle is rendered invalid. Just before removing a dynamic library or bundle in this way, any termina-
tion routines in it are called. handle is the value returned by a previous call to dlopen.
Prior to Mac OS X 10.5, only bundles could be unloaded. Starting in Mac OS X 10.5, dynamic libraries may also be unloaded. There are a cou-
ple of cases in which a dynamic library will never be unloaded: 1) the main executable links against it, 2) An API that does not supoort
unloading (e.g. NSAddImage()) was used to load it or some other dynnamic library that depends on it, 3) the dynamic library is in dyld's
shared cache.
RETURN VALUES
If dlclose() is successful, it returns a value of 0. Otherwise it returns -1, and sets an error string that can be retrived with dlerror().
