Sometimes I see header files of the form.
#include <sys/sysinfo.h> // I found this on my system under /usr/include/sys/sysinfo.h. Is that all the "sys/" means?
What is this called and why are these header files different from most others like
#include <stdio.h>
Maybe a group of related header files been grouped under the label of 'sys', but if I try something like "man pci" (there's a pci.h header in /usr/include/sys/ there is no entry.
#include <sys/sysinfo.h> // I found this on my system under /usr/include/sys/sysinfo.h. Is that all the "sys/" means?
