CREATE_MODULE(2) Linux Programmer's Manual CREATE_MODULE(2)
create_module - create a loadable module entry
caddr_t create_module(const char *name, size_t size);
Note: No declaration of this function is provided in glibc headers; see
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.
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
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
This system call is present on Linux only up until kernel 2.4; it was
removed in Linux 2.6.
create_module() is Linux-specific.
The create_module() system call is not supported by glibc. No declara-
tion 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
delete_module(2), init_module(2), query_module(2)
