NAME

       bcmp - memory operations (LEGACY)

SYNOPSIS

       #include <strings.h>

       int bcmp(const void *s1, const void *s2, size_t n);

DESCRIPTION

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

RETURN VALUE

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

ERRORS

       No errors are defined.

       None.

APPLICATION USAGE

       The memcmp() function is preferred over this function.

       For maximum portability, it is recommended to replace  the  function  call  to  bcmp()  as
       follows:

              #define bcmp(b1,b2,len) memcmp((b1), (b2), (size_t)(len))

RATIONALE

       None.

FUTURE DIRECTIONS

       This function may be withdrawn in a future version.
