I have a long-living application with frequent memory allocation-deallocation. Will any malloc implementation return freed memory back to the system?
I have two processes P1 and P2. I have this large read-only resource, called \"R\" that I want both P1 and P2 to have access to.
I have a program. I want it to be able to mmap a particular region of memory over different runs. I have the source code of the program. C/C++
Exposition: I am on Linux / Mac. Part of my code is in Java, part of my code is in C++. They both have the same file mmapped for fast communication.
Helllo, I would like to share small amounts of data (< 1K) between python and processes. The data is physical pc/104 IO data which changes rapidly and often (24x7x365). There will be a single \"ser
I have several fastcgi processes that are supposed to share data. The data is bound to a session (a unique session id string) and should be able to survive a server reboot. Depending on the number o

When we map a file to memory, a system call is required. Do subsequent accesses to the file require system calls or is the virtual memory page of the process mapped to the actual page cache in memory?
It was recently asked how to do a file slurp in python, and the accepted answer suggested something like:
Im struggling to read(and write开发者_开发知识库) to HW registers from Linux user space. The goal is to configure some GPIO pins from and be able to set and read this pins.
