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.

PLDD(1) Linux User Manual PLDD(1)
NAME
pldd - display dynamic shared objects linked into a process
SYNOPSIS
pldd pid
pldd option
DESCRIPTION
The pldd command displays a list of the dynamic shared objects that are linked into the process with the specified process ID. The list
includes the libraries that have been dynamically loaded using dlopen(3).
OPTIONS
-?, --help
Display program help message.
--usage
Display a short usage message.
-V, --version
Display the program version.
EXIT STATUS
On success, pldd exits with the status 0. If the specified process does not exist, the user does not have permission to access its dynamic
shared object list, or no command-line arguments are supplied, pldd exists with a status of 1. If given an invalid option, it exits with
the status 64.
VERSIONS
pldd is available since glibc 2.15.
CONFORMING TO
The pldd command is not specified by POSIX.1. Some other systems have a similar command.
NOTES
The command
lsof -p PID
also shows output that includes the dynamic shared objects that are linked into a process.
The gdb(1) info shared command also shows the shared libraries being used by a process, so that one can obtain similar output to pldd using
a command such as the following (to monitor the process with the specified pid):
$ gdb -ex "set confirm off" -ex "set height 0" -ex "info shared"
-ex "quit" -p $pid | grep '^0x.*0x'
BUGS
Since glibc 2.19, pldd is broken: it just hangs when executed. It is unclear if it will ever be fixed.
EXAMPLE
$ echo $$ # Display PID of shell
1143
$ pldd $$ # Display DSOs linked into the shell
1143: /usr/bin/bash
