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 function 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 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 (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

       The create_module() system call is not supported by glibc.  No declaration is provided  in
       glibc  headers,  but, through a quirk of history, glibc does export an ABI for this system
       call.  Therefore, in order to employ this  system  call,  it  is  sufficient  to  manually
       declare  the  interface  in your code; alternatively, you can invoke the system call using
       syscall(2).
