NAME
DECLARE_MODULE — kernel module declaration macroSYNOPSIS
#include <sys/param.h> #include <sys/kernel.h> #include <sys/module.h> DECLARE_MODULE(name, moduledata_t data, sub, order);DESCRIPTION
The DECLARE_MODULE() macro declares a generic kernel module. It is used to register the module with the system, using the SYSINIT() macro. DECLARE_MODULE() is usually used within other macros, such as DRIVER_MODULE(9), DEV_MODULE(9) and SYSCALL_MODULE(9). Of course, it can also be called directly, for example in order to implement dynamic sysctls. The arguments it expects are: name The module name, which will be used in the SYSINIT() call to identify the module. data A moduledata_t structure, which contains two main items, the official name of the module name, which will be used in the module_t structure and a pointer to the event handler function of type modeventhand_t. sub An argument directed to the SYSINIT() macro. Valid values for this are contained in the sysinit_sub_id enumeration (see <sys/kernel.h>) and specify the type of system startup interfaces. The DRIVER_MODULE(9) macro uses a value of SI_SUB_DRIVERS here for example, since these modules contain a driver for a device. For kernel modules that are loaded at runtime, a value of SI_SUB_EXEC is common. order An argument for SYSINIT(). It represents the KLDs order of initialization within the subsystem. Valid values are defined in the sysinit_elem_order enumeration (<sys/kernel.h>).SEE ALSO
