BCMP(3P)                   POSIX Programmer's Manual                  BCMP(3P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
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; other-
       wise, 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       This function may be withdrawn in a future version.
