CREATE_MODULE(2) Linux Programmer's Manual CREATE_MODULE(2)
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 in-
formation.
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 ver-
sions before 2.23 did export an ABI for this system call. Therefore,
in order to employ this system call, it was sufficient to manually de-
clare the interface in your code; alternatively, you could invoke the
system call using syscall(2).
