NAME    [Toc]    [Back]

       init_module - initialize a loadable module entry

SYNOPSIS    [Toc]    [Back]

       #include <linux/module.h>

       int init_module(const char *name, struct module *image);

DESCRIPTION    [Toc]    [Back]

       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, i.e. relocated with the rest of the module.

       This system call is only open to the superuser.

RETURN VALUE    [Toc]    [Back]

       On  success,  zero  is returned.  On error, -1 is returned and errno is
       set appropriately.

ERRORS    [Toc]    [Back]

       EPERM  The user is not the superuser.

       ENOENT No module by that name exists.

       EINVAL Some image slot 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.


       EBUSY  The module's initialization routine failed.

       EFAULT name or image is outside the program's accessible address space.
