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.

       The following sections are informative.

EXAMPLES

       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       This function may be withdrawn in a future version.
