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);

SYSCALL_MODULE(9)					   BSD Kernel Developer's Manual					 SYSCALL_MODULE(9)

NAME

     SYSCALL_MODULE -- syscall kernel module declaration macro

SYNOPSIS

     #include <sys/param.h>
     #include <sys/kernel.h>
     #include <sys/proc.h>
     #include <sys/module.h>
     #include <sys/sysent.h>

     SYSCALL_MODULE(name, int *offset, struct sysent *new_sysent, modeventhand_t evh, void *arg);

DESCRIPTION

     The SYSCALL_MODULE() macro declares a new syscall.  SYSCALL_MODULE() expands into a kernel module declaration named as name.

     The rest of the arguments expected by this macro are:

     offset	 A pointer to an int which saves the offset in struct sysent where the syscall is allocated.

     new_sysent  is a pointer to a structure that specifies the function implementing the syscall and the number of arguments this function needs
		 (see <sys/sysent.h>).

     evh	 A pointer to the kernel module event handler function with the argument arg.  Please refer to module(9) for more information.

     arg	 The argument passed to the callback functions of the evh event handler when it is called.

EXAMPLES

     A minimal example for a syscall module can be found in /usr/share/examples/kld/syscall/module/syscall.c.
