I want to add new syscall to freeBSD kernel and I want to change syscalls.master file in /usr/src/sys/kern/syscalls.master. But this file is not existing in this path and /usr/src path is empty. What is wrong in this scenario?
Thanks in advance!
The first work for creating a system call is getting the source from svn.
The first step is to determine which version of FreeBSD is being used with uname command.
uname -r
I have 10.3-RELEASE of freeBSD then I get this version from svn with the following command.
svnlite checkout https://svn.freebsd.org/base/releng/10.3 /usr/src
