NAME

       create_module - create a loadable module entry

SYNOPSIS

       #include <linux/module.h>

       caddr_t create_module(const char *name, size_t size);

       Note: No declaration of this system call is provided in glibc headers; see NOTES.

DESCRIPTION

       Note: This system call is present only in kernels before Linux 2.6.

       create_module()  attempts  to  create  a loadable module entry and reserve the kernel memory that will be
       needed to hold the module.  This system call requires privilege.

RETURN VALUE

       On success, returns the kernel address at which the module will reside.  On error,  -1  is  returned  and
       errno is set appropriately.

ERRORS

       EEXIST A module by that name already exists.

       EFAULT name is outside the program's accessible address space.

       EINVAL The requested size is too small even for the module header information.

       ENOMEM The kernel could not allocate a contiguous block of memory large enough for the module.

       ENOSYS create_module() is not supported in this version of the kernel (e.g., the kernel is version 2.6 or
              later).

       EPERM  The caller was not privileged (did not have the CAP_SYS_MODULE capability).

VERSIONS

       This system call is present on Linux only up until kernel 2.4; it was removed in Linux 2.6.

CONFORMING TO

       create_module() is Linux-specific.

NOTES

       This  obsolete  system call is not supported by glibc.  No declaration is provided in glibc headers, but,
       through a quirk of history, glibc  versions  before  2.23  did  export  an  ABI  for  this  system  call.
       Therefore,  in  order  to employ this system call, it was sufficient to manually declare the interface in
       your code; alternatively, you could invoke the system call using syscall(2).
