BZERO(9F) Kernel Functions for Drivers BZERO(9F)
bzero - clear memory for a given number of bytes
#include <sys/types.h>
#include <sys/ddi.h>
void bzero(void *addr, size_t bytes);
Architecture independent level 1 (DDI/DKI).
addr
Starting virtual address of memory to be cleared.
bytes
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.

Writing Device Drivers
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.
