So, I think I'm okay with the syscall() changes in the SYNOPSIS.
It might just take me a moment to get used to them. However, I do
wonder if it is worth retaining a comment in the SYSNOPSIS,
something like:
SYNOPSIS
#include <asm/prctl.h> /* Definition of ARCH_* constants */
#include <sys/syscall.h> /* Definition of SYS_* constants */
#include <unistd.h>
int syscall(SYS_arch_prctl, int code, unsigned long addr);
int syscall(SYS_arch_prctl, int code, unsigned long *addr);
Note: glibc provides no wrapper for arch_prctl(), necessitating
the use of syscall(2).
Without something like this, the reader may be puzzled at the use of
syscall().
What do you think?
Yes. I had doubts, and you confirmed them. I'll add that.
Thanks,
Alex
