INIT_MODULE(2) Linux Programmer's Manual INIT_MODULE(2)NAMEinit_module - initialize a loadable module entry
SYNOPSIS
#include <linux/module.h>
int init_module(const char *name, struct module *image);
DESCRIPTIONinit_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 appro‐
priate for kernel space, that is, relocated with the rest of the mod‐
ule.
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 TOinit_module() is Linux-specific.
