bzero
—
write zeroes to a byte string
Standard C Library (libc, -lc)
#include <strings.h>
void
bzero
(void
*b, size_t
len);
The bzero
() function writes len
zero bytes to the string b. If len
is zero, bzero
() does nothing.
The bzero
() function conforms to IEEE
Std 1003.1-2001 (“POSIX.1”). The IEEE
Std 1003.1-2004 (“POSIX.1”) revision marked it as legacy
and recommended the use of
memset(3) instead. The
IEEE Std 1003.1-2008 (“POSIX.1”)
revision removed bzero
() from the specification.
A bzero
() function appeared in
4.3BSD.
