NAME
explicit_bzero — write zeroes to a byte stringLIBRARY
library “libbsd”SYNOPSIS
#include <string.h> (See libbsd(7) for include usage.)void
explicit_bzero(void *buf, size_t len);
DESCRIPTION
The explicit_bzero() function writes len zero bytes to the string buf. If len is zero, explicit_bzero() does nothing. The explicit_bzero() variant behaves the same as the bzero() function, but will not be removed by a compiler's dead store optimization pass, making it useful for clearing sensitive memory such as a password.SEE ALSO
