C memory layout

resres · 03-14-2019, 02:53 PM

How I can see how the c program layouts it`s memory(how and where is stored in cache, ram ,swap). I want to see the mapping of an array to the cache/ram .

For starters run it under the debugger and view the addresses.

As far as swap goes, I don't know if there are any programming API functions for monitoring it, but I assume there may be some.

Recommend you check the Linux kernel mem source for that information.

Check /proc/pid/maps. In man proc it says:

Code:

A file containing the currently mapped memory regions and their access permissions.  See mmap(2) for some further information about memory mappings.
