MODULE_DEPEND9
Set kernel module dependencies
Usage
#include <sys/param.h>
#include <sys/module.h>
MODULE_DEPEND(name, moddepend, int minversion, int prefversion, int maxversion);
Overview
The MODULE_DEPEND() macro sets a dependency on another kernel module with name moddepend, which has registered its version with MODULE_VERSION().
The 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 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);
