is linux header <linux/sysctl.h> deprecated ?
I read this on man 2 sysctl:
This system call first appeared in Linux 1.3.57. It was removed in Linux 5.5; glibc support was removed in version 2.32.
I misunderstood this line?
How to change system parameters in future (after removal)?

- It has the
deprecatedattribute.
[[deprecated]] int _sysctl(struct __sysctl_args *args);
- The description states that it no longer exists on current kernels.
This system call no longer exists on current kernels!
- “NOTES” suggest using
/proc/sysinterface:
Use of this system call was long discouraged: since Linux 2.6.24,
uses of this system call result in warnings in the kernel log,
and in Linux 5.5, the system call was finally removed. Use the
/proc/sys interface instead.
and the man page links to this: proc.
So yes, it is deprecated.
