create_module - create a loadable module entry
#include <linux/module.h>
[[deprecated]] caddr_t create_module(const char *name, size_t size);
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.
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.
- 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).
This system call is present only up until Linux 2.4; it was removed in Linux
2.6.
create_module() is Linux-specific.
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).
