int
bcmp(const void *b1, const void *b2, size_t len)
)
interface is obsolete.
Do not add new code using it.
It will soon be purged.
Use
memcmp(9)
instead.
(The
bcmp()
function is now a macro for
memcmp(9).)
The
bcmp()
function
compares byte string
b1
against byte string
b2,
returning zero if they are identical, non-zero otherwise.
Both strings are assumed to be
len
bytes long.
Zero-length strings are always identical.
The strings may overlap.
