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);
