    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.
