Hi Michael, As I told you some time ago, I liked the style of FreeBSD for specifying where a function comes from. See for example: <https://www.freebsd.org/cgi/man.cgi?query=open&apropos=0&sektion=2&manpath=FreeBSD+12.2-RELEASE+and+Ports&arch=default&format=html> and <https://www.freebsd.org/cgi/man.cgi?query=gamma&apropos=0&sektion=3&manpath=FreeBSD+12.2-RELEASE+and+Ports&arch=default&format=html>. I wrote a few pages to cover most cases: - A syscall needing syscall(2). - A syscall wrapped by a library other than glibc. - A syscall wrapped by glibc. - A math function. What do you think about it?
