create_module – create a loadable module entry

USAGE
       #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.

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

CONFORMING TO
       create_module() is Linux specific.

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