NAME
init_module - initialize a loadable module entry
SYNOPSIS
#include <linux/module.h>
int init_module(const char *name, struct module *image);
DESCRIPTION
init_module()
loads the relocated module image into kernel space and runs the
module's
init
function.
The module image begins with a module structure and is followed by
code and data as appropriate.
The module structure is defined as follows:
struct module {
unsigned long size_of_struct;
struct module *next;
const char *name;
unsigned long size;
long usecount;
unsigned long flags;
unsigned int nsyms;
unsigned int ndeps;
struct module_symbol *syms;
struct module_ref *deps;
struct module_ref *refs;
int (*init)(void);
void (*cleanup)(void);
const struct exception_table_entry *ex_table_start;
const struct exception_table_entry *ex_table_end;
#ifdef __alpha__
unsigned long gp;
#endif
};
All of the pointer fields, with the exception of
next
and
refs,
are expected to point within the module body and be
initialized as appropriate for kernel space, that is, relocated with
the rest of the module.
This system call requires privilege.
RETURN VALUE
On success, zero is returned.
On error, -1 is returned and
errno
is set appropriately.
ERRORS
- EBUSY
-
The module's initialization routine failed.
- EFAULT
-
name
or
image
is outside the program's accessible address space.
- EINVAL
-
Some
image
slot is filled in incorrectly,
image->name
does not correspond to the original module name, some
image->deps
entry does not correspond to a loaded module,
or some other similar inconsistency.
- ENOENT
-
No module by that name exists.
- EPERM
-
The caller was not privileged
(did not have the
CAP_SYS_MODULE
capability).
CONFORMING TO
init_module()
is Linux-specific.
