BZERO(3) BSD Library Functions Manual BZERO(3)NAME
bzero -- write zeroes to a byte string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <strings.h>
void
bzero(void *b, size_t len);
DESCRIPTION
The bzero() function writes len zero bytes to the string b. If len is zero, bzero() does nothing.
SEE ALSO memset(3), swab(3)STANDARDS
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.
HISTORY
A bzero() function appeared in 4.3BSD.
BSD April 29, 2010 BSD

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This function may be withdrawn in a future version.
