pub fn getregs(pid: Pid) -> Result<user_regs_struct>Expand description
Get user registers, as with ptrace(PTRACE_GETREGS, ...)
Note that since PTRACE_GETREGS are not available on all platforms (as in ptrace(2)),
ptrace(PTRACE_GETREGSET, pid, NT_PRSTATUS, ...) is used instead to achieve the same effect
on aarch64 and riscv64.
