mod_remove(9f)

mod_install(9F)                Kernel Functions                mod_install(9F)



NAME
       mod_install, mod_remove, mod_info, mod_modname - add, remove or query a
       loadable module

SYNOPSIS
       #include <sys/modctl.h>

       int mod_install(struct modlinkage *modlinkage);


       int mod_remove(struct modlinkage *modlinkage);


       int mod_info(struct modlinkage *modlinkage,
            struct modinfo *modinfo);


       const char *mod_modname(struct modlinkage *modlinkage);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI).

PARAMETERS
       modlinkage    Pointer to the  loadable  module's  modlinkage  structure
                     which  describes  what  type(s)  of  module  elements are
                     included in this loadable module.


       modinfo       Pointer to the modinfo structure passed to _info(9E).


DESCRIPTION
       mod_install() must be called from a module's _init(9E) routine.


       mod_remove() must be called from a module's _fini(9E) routine.


       mod_info() must be called from a module's _info(9E) routine.


       mod_modname() can be called from any module routine.


       When _init(9E) is executing, its call to  mod_install()  enables  other
       threads  to  call  attach(9E) even prior to mod_install() returning and
       _init(9E) completion. From a programming standpoint this means that all
       _init(9E)   initialization   must  occur  prior  to  _init(9E)  calling
       mod_install(). If mod_install() fails (non-zero return value), any ini‐
       tialization must be undone.


       When  _fini(9E)  is executing, another thread may call attach(9E) prior
       to _fini(9E) calling mod_remove(). If  this  occurs,  the  mod_remove()
       fails (non-zero return). From a programming standpoint, this means that
       _init(9E) initializations should only  be  undone  after  a  successful
       return from mod_remove().


       To  query  the  name of a module, use mod_modname(). If the module is a
       driver, the module name is the same as the driver name.  This  function
       can  be  used to avoid compiled-in knowledge of the module name, and is
       of particular  use  when  _init(9E)  needs  to  call  a  function  like
       kstat_create(9F).

RETURN VALUES
       mod_install()  and  mod_remove()  return 0 upon success and non-zero on
       failure.


       mod_info() returns a non-zero value on success and 0 upon failure.


       mod_modname() returns the name of the module. The returned name remains
       valid as long as the module remains loaded.

EXAMPLES
       See _init(9E) for an example that uses these functions.

SEE ALSO
