NAME

       create_module - create a loadable module entry

SYNOPSIS

       #include <linux/module.h>

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

DESCRIPTION

       Note: This system call is present only 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 to indicate the error.

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., Linux 2.6  or
              later).

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

VERSIONS

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

STANDARDS

       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 versions before glibc 2.23 did  export  an
       ABI  for  this  system  call.   Therefore,  in  order  to  employ this system call, it was
       sufficient to manually declare the interface in your code; alternatively, you could invoke
       the system call using syscall(2).
