#include <linux/module.h> 



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

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.

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

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

create_module() is Linux specific.

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