SYNOPSIS

modunload −i module_id [ −e exec_file ]

AVAILABILITY

SUNWcsu

DESCRIPTION

modunload unloads a loadable module from the running system.  The module_id is the ID of the module as shown by modinfo(1M).  If ID is 0, all modules that were autoloaded which are unloadable, are unloaded.  Modules loaded by modload(1M) are not affected. 

OPTIONS

−i module_id Specify the module to be unloaded. 

−e exec_file Specify the name of a shell script or executable image file to be executed before the module is unloaded.  The first argument passed is the module id (in decimal).  There are two additional arguments that are module specific.  For loadable drivers, the second and third arguments are the block major and character major numbers respectively.  For loadable system calls, the second argument is the system call number.  For loadable exec classes, the second argument is the index into the execsw table.  For loadable filesystems, the second argument is the index into the vfssw table. For loadable streams modules, the second argument is the index into the fmodsw table.  For loadable scheduling classes, the second argument is the index into the class array.  Minus one is passed for an argument that does not apply.
