a repository to share little apps and experiences while using linux
Memchech.c
My server had memory allocation problems while free and htop commands were showing lots of available memory. I decided to write a program that just allocates memory and see where it fails to actually see what is the unreserved memory. When i only allocated memory free and htop did not show any increase in usage, only after i used the memory with memset it started to show. However despite not being recognised by free and htop the memory is reserved and prevents apps to allocate. So i changed the program to allocate and this way could see how much memory is actually available for allocation. There might be many better ways for this tho since i am no expert in unix systems.
