NAME

create_module - create a loadable module entry  

SYNOPSIS

#include <linux/module.h>

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

DESCRIPTION

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

VERSIONS

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

CONFORMING TO

create_module() is Linux-specific.
