Linux 2.6 - man page for bcmp (linux section 3posix)

BCMP(P) 			    POSIX Programmer's Manual				  BCMP(P)

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  fol-
       lows:

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

RATIONALE
       None.

FUTURE DIRECTIONS
       This function may be withdrawn in a future version.
