#include <sys/types.h> #include <sys/ddi.h> void bzero(void *addr, size_t bytes);
Architecture independent level 1 (DDI/DKI).
Starting virtual address of memory to be cleared.
The number of bytes to clear starting at addr.
The bzero() function clears a contiguous portion of memory by filling it with zeros.
The bzero() function can be called from user, interrupt, or kernel context.
The address range specified must be within the kernel space. No range checking is done. If an address outside of the kernel space is selected, the driver may corrupt the system in an unpredictable way.
