module_depend(9)

NAME

MODULE_DEPEND - set kernel module dependencies

SYNOPSIS

#include <sys/param.h>
#include <sys/module.h>
MODULE_DEPEND(name,   moddepend,   int    minversion,    int
prefversion,
        int maxversion);

DESCRIPTION

The MODULE_DEPEND() macro sets a dependency on another ker

nel module with
name moddepend, which has registered its version with

MODULE_VERSION

The MODULE_DEPEND() macro provides hints to the kernel load

er(8) and to
the kernel linker to ensure that the named dependency is

loaded prior to
the existing module. It does not change or dictate the or

der in which
modules are initialized at runtime.

Three versions must be specified for moddepend:

minversion The minimum version on which the current

module can

depend.

maxversion The maximum version on which the current

module can

depend.

prefversion The preferred version on which the current

module can

depend.

EXAMPLES

MODULE_DEPEND(foo, bar, 1, 3, 4);
