MODULE_DEPEND(9)	 BSD Kernel Developer's Manual	      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 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);
