I/O access to virtual memory contents of processes
Read and write data from/to the current process and other processes. This can be used for process monitoring, debugging, testing, communication, etc.
Examples
Reading the stack of the currently running process, through this library:

Writing to the heap of the currently running process, through this library:

Safety
Memory safety
Writing to the virtual memory of a process is a potentially unsafe operation because it may introduce memory unsafety in that process, and may lead to unexpected states in that process. This is even more dangerous when the target process is the currently running process.
Running processes
Performing I/O on a running process is not recommended, because the
layout of its virtual memory can change at any time, or the process
could simply terminate and vanish.
Consider pausing all threads of the specified process before performing
I/O on it. This can usually be done via the SIGSTOP
and SIGCONT
POSIX signals.
Platform-specific notes
For the moment, only Linux is supported.
