NAME
       modlinkage - module linkage structure

SYNOPSIS
       #include <sys/modctl.h>

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI)

DESCRIPTION
       The modlinkage structure is provided by the module writer to the routines that install, remove, and retrieve information from a module. See
       _init(9E), _fini(9E), and _info(9E).

STRUCTURE MEMBERS
       int    ml_rev
       void   *ml_linkage[4];

       ml_rev	       Is the revision of the loadable modules system.	This must have the value MODREV_1 .

       ml_linkage      Is a null-terminated array of pointers to linkage structures. Driver modules have only one linkage structure.
