NAME

MODULE_DEPEND - set kernel module dependencies

SYNOPSIS

In sys/param.h In sys/module.h Fn MODULE_DEPEND name moddepend int minversion int prefversion int maxversion

DESCRIPTION

The Fn MODULE_DEPEND macro sets a dependency on another kernel module with name Fa moddepend , which has registered its version with Fn MODULE_VERSION .

The Fn MODULE_DEPEND macro provides hints to the kernel loader(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 order in which modules are initialized at runtime.

Three versions must be specified for Fa moddepend :

Fa minversion

The minimum version on which the current module can depend.

Fa maxversion

The maximum version on which the current module can depend.

Fa prefversion

The preferred version on which the current module can depend.

EXAMPLES

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