NAME¶

create_module - create a loadable module entry

SYNOPSIS¶

#include <linux/module.h>

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

DESCRIPTION¶

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.

EPERM

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

VERSIONS¶

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

CONFORMING TO¶

create_module() is Linux-specific.

SEE ALSO¶

delete_module(2), init_module(2), query_module(2)
