NAME

       bcmp - compare two byte arrays

SYNOPSIS

       #include <sys/types.h>
       #include <sys/ddi.h>

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

INTERFACE LEVEL

       Architecture independent level 1 (DDI/DKI).

PARAMETERS

       s1     Pointer to the first character string.

       s2     Pointer to the second character string.

       len    Number of bytes to be compared.

DESCRIPTION

       The bcmp() function compares two byte arrays of length len.

RETURN VALUES

       The bcmp() function returns 0 if the arrays are identical, or 1 if they are not.

CONTEXT

       The bcmp() function can be called from user, interrupt, or kernel context.

SEE ALSO

NOTES

       Unlike strcmp(9F), bcmp() does not terminate when it encounters a null byte.

NAME

       bcmp - compare byte sequences

SYNOPSIS

       #include <strings.h>

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

DESCRIPTION

       The  bcmp() function compares the two byte sequences s1 and s2 of length n each.  If they are equal, and in particular if n is zero, bcmp()
       returns 0.  Otherwise it returns a nonzero result.

RETURN VALUE

       The bcmp() function returns 0 if the byte sequences are equal, otherwise a nonzero result is returned.

CONFORMING TO

       4.3BSD.	This function is deprecated (marked as LEGACY in POSIX.1-2001): use memcmp(3) in new programs.	POSIX.1-2008 removes the  specifi-
       cation of bcmp().
