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 system call 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 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., 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

       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 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).
