NAME

6       create_module - create a loadable module entry
7

SYNOPSIS

9       #include <linux/module.h>
10
11       [[deprecated]] caddr_t create_module(const char *name, size_t size);
12

DESCRIPTION

14       Note: This system call is present only before Linux 2.6.
15
16       create_module()  attempts to create a loadable module entry and reserve
17       the kernel memory that will be needed to hold the module.  This  system
18       call requires privilege.
19

RETURN VALUE

21       On success, returns the kernel address at which the module will reside.
22       On error, -1 is returned and errno is set to indicate the error.
23

ERRORS

25       EEXIST A module by that name already exists.
26
27       EFAULT name is outside the program's accessible address space.
28
29       EINVAL The requested size is too small even for the module  header  in‐
30              formation.
31
32       ENOMEM The kernel could not allocate a contiguous block of memory large
33              enough for the module.
34
35       ENOSYS create_module() is not supported in this version of  the  kernel
36              (e.g., Linux 2.6 or later).
37
38       EPERM  The  caller  was not privileged (did not have the CAP_SYS_MODULE
39              capability).

STANDARDS

42       Linux.

HISTORY

45       Removed in Linux 2.6.
46
47       This obsolete system call is not supported by glibc.  No declaration is
48       provided  in glibc headers, but, through a quirk of history, glibc ver‐
49       sions before glibc 2.23 did export an ABI for this system call.  There‐
50       fore,  in  order to employ this system call, it was sufficient to manu‐
51       ally declare the interface in your code; alternatively, you  could  in‐
52       voke the system call using syscall(2).
