I am trying to modify the getpid() system call definition file for an assignment, however I am having trouble locating where this file is. Could someone be able to tell me where the location of the headers are (always wondered that) and where I can find the actual definitions in the kernel. Thanks!
Search the Web for "man getpid".
Try
Code:locate unistd.h
I ran the "locate unistd.h" command but all I am able to find after running that is the function declarations. what should I run with "locate" to find the definitions file?
You'll have to download your systems C lib, which most likely is GLIBC: Index of /gnu/glibc
cd into the main source code dir, and use:
Code:find ./ -iname getpid.c
