I was recently looking in libc when I noticed a few things about system calls: 1) brk and sbrk are implemented atop brk_, which is not documented 2) the seek function seems to be a system call, but the alpha folder defines a function seek which calls _seek 3) Some items in that file have underscores, like BRK_ and _READ This leads me to the following question: what exactly are the system calls in Plan 9? Thanks.
