NAME

6       bcmp - memory operations (LEGACY)
7

SYNOPSIS

9       #include <strings.h>
10
11       int bcmp(const void *s1, const void *s2, size_t n);
12
13

DESCRIPTION

15       The bcmp() function shall compare the first n bytes of the area pointed
16       to by s1 with the area pointed to by s2.
17

RETURN VALUE

19       The bcmp() function shall return 0 if s1 and s2 are  identical;  other‐
20       wise,  it  shall  return non-zero. Both areas are assumed to be n bytes
21       long. If the value of n is 0, bcmp() shall return 0.
22

APPLICATION USAGE

32       The memcmp() function is preferred over this function.
33
34       For maximum portability, it is recommended to replace the function call
35       to bcmp() as follows:
36
37
38              #define bcmp(b1,b2,len) memcmp((b1), (b2), (size_t)(len))
39

RATIONALE

41       None.
42

FUTURE DIRECTIONS

44       This function may be withdrawn in a future version.
