-.TH sysctl 2 2023-10-31 "Linux man-pages 6.7"
-.SH NAME
-sysctl \- read/write system parameters
-.SH SYNOPSIS
-.nf
-.B #include <unistd.h>
-.B #include <linux/sysctl.h>
-.P
-.BI "[[deprecated]] int _sysctl(struct __sysctl_args *" args );
-.fi
-.SH DESCRIPTION
-.B This system call no longer exists on current kernels!
-See NOTES.
-.P
-The
-.BR _sysctl ()
-call reads and/or writes kernel parameters.
-For example, the hostname,
-or the maximum number of open files.
-The argument has the form
-.P
-.in +4n
-.EX
-struct __sysctl_args {
-    int    *name;    /* integer vector describing variable */
-    int     nlen;    /* length of this vector */
-    void   *oldval;  /* 0 or address where to store old value */
-    size_t *oldlenp; /* available room for old value,
-                        overwritten by actual size of old value */
-    void   *newval;  /* 0 or address of new value */
-    size_t  newlen;  /* size of new value */
-};
-.EE
-.in
-.P
-This call does a search in a tree structure, possibly resembling
-a directory tree under
-.IR /proc/sys ,
-and if the requested item is found calls some appropriate routine
-to read or modify the value.
-.SH RETURN VALUE
-Upon successful completion,
-.BR _sysctl ()
-returns 0.
-Otherwise, a value of \-1 is returned and
-.I errno
-is set to indicate the error.
-.SH ERRORS
-.TP
-.B EACCES
-.TQ
-.B EPERM
-No search permission for one of the encountered "directories",
-or no read permission where
-.I oldval
-was nonzero, or no write permission where
-.I newval
-was nonzero.
-.TP
-.B EFAULT
-The invocation asked for the previous value by setting
-.I oldval
-non-NULL, but allowed zero room in
-.IR oldlenp .
-.TP
-.B ENOTDIR
-.I name
-was not found.
-.SH STANDARDS
-Linux.
-.SH HISTORY
-Linux 1.3.57.
-Removed in Linux 5.5, glibc 2.32.
-.P
-It originated in
-4.4BSD.
-Only Linux has the
-.I /proc/sys
-mirror, and the object naming schemes differ between Linux and 4.4BSD,
-but the declaration of the
-.BR sysctl ()
-function is the same in both.
-.SH NOTES
-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
-.I /proc/sys
-interface instead.
-.P
-Note that on older kernels where this system call still exists,
-it is available only if the kernel was configured with the
-.B CONFIG_SYSCTL_SYSCALL
-option.
-Furthermore, glibc does not provide a wrapper for this system call,
-necessitating the use of
-.BR syscall (2).
-.SH BUGS
-The object names vary between kernel versions,
-making this system call worthless for applications.
-.P
-Not all available objects are properly documented.
-.P
-It is not yet possible to change operating system by writing to
-.IR /proc/sys/kernel/ostype .
