July 7, 2001 BZERO 9

### NAME

bzero - write zeroes to a byte string

### SYNOPSIS

```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The bzero(``) interface is obsolete.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.

### SEE ALSO

memset(9)
