Hi Lior thanks for your time and code example. Shachar Shemesh explained to me couple of simple things I forgotten. You can find his replies in this thread but the bottom line : I do not need to signal kernel.Kernel memory manager will discover that pages are not active ( each page have active

That's not true either, actually. Mmap absolutely does not need
a file
Shachar , you are 100%/ right ! Since I knew that mmap needs file descriptor I assumed ( and did not checked man page) that munmap need file descriptor. Great !!Thanks, Thanks, Thanks! 04.01.2019, 22:30, "Shachar Shemesh" : On 27/12/2018 15:34, Lev Olshvang wrote:Can you elaborate why I can not

Can you elaborate why I can not write new system call to unmap

Why would you need a system call to do this?
Well,
Shahar, Thank you very much.I am going to use your advise ( actually I am advising on this to other team but I will ping them until they change static mapping to dynamic in their build system) I will update the list on the results but your are absolutely correct that memory manager will do
Hello Greg,
Thanks for you your reply.
It help me to better express my question
From the application I can access /proc/self/maps and see which memory is
mapped for my library I do not intend to use after application passes init
phase.
I would like to unmap this memory region, but since I do

So this is a question.

Boker tov, Thanks for all of your replies that helped me to understand what question I really wanted to ask. So this is a question. I have C++ program which calls many services of third party library.This library is needed only on initialization phase of my program. Linker has resolved symbols
Also if we are speaking Linux, the OS in general have very aggressive
caching policy.
Everything is remains in cache until it it fills up or it cleaned up
externally.
AFAIK there's no negative effects on performance.
That is not touching the programming that I know little about.

Hi All,
I have an executable (C++) which is the exclusive user of the some shared library that it uses only during the initialization phase.
I would like to free memory used by this shared library, because I am running
