BZERO(9) BSD Kernel Developer's Manual BZERO(9)NAME
bzero -- write zeroes to a byte string
SYNOPSIS
#include <sys/systm.h>
void
bzero(void *b, size_t len);
DESCRIPTION
The bzero() interface is obsolete. Do not add new code using it. It will soon be purged. Use memset(9) instead. (The bzero() function is
now a macro for memset(9).)
The bzero() function writes len zero bytes to the string b. If len is zero, bzero() does nothing.

NAME
bzero - memory operations (LEGACY)
SYNOPSIS
#include <strings.h>
void bzero(void *s, size_t n);
DESCRIPTION
The bzero() function shall place n zero-valued bytes in the area pointed to by s.
RETURN VALUE
The bzero() function shall not return a value.
ERRORS
No errors are defined.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
The memset() function is preferred over this function.
For maximum portability, it is recommended to replace the function call to bzero() as follows:
#define bzero(b,len) (memset((b), ' ', (len)), (void) 0)
RATIONALE
None.
FUTURE DIRECTIONS
This function may be withdrawn in a future version.
