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 *s, size_t n);
DESCRIPTION
The bzero() function writes n zeroed bytes to the string s. If n is zero, bzero() does nothing.
SEE ALSO memset(3), swab(3)HISTORY
A bzero() function appeared in 4.3BSD. Its prototype existed previously in <string.h> before it was moved to <strings.h> for IEEE Std
1003.1-2001 (``POSIX.1'') compliance.
bzero() was deprecated in IEEE Std 1003.1-2001 (``POSIX.1'') and removed in IEEE Std 1003.1-2008 (``POSIX.1'').

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This function may be withdrawn in a future version.
