Byte Arrays

These functions operate on 8-bit byte arrays, not 16-bit characters.

int memcmp(byte *str1, byte *str2, int num) int memfcmp(byte *str1, byte *str2, int num) memcpy(byte *tostr, byte *fromstr, int num) memset(byte *ptr, char value, int count)
The memcmp( ) and memfcmp( ) primitives compare 8-bit bytes, not 16-bit characters like the compare_chars( ) and strcmp( ) primitives do. The memfcmp( ) primitive ignores case, memcmp( ) doesn't. They return values like the others, and don't stop comparing when an array element has a zero value, as strcmp( ) does.

The memcpy( ) primitive copies exactly num bytes from the second byte array to the first.

The memset( ) primitive sets all the count bytes in a byte array ptr to the given value.

chars_to_bytes(byte *b, char *s) bytes_to_chars(char *s, byte *b)
The chars_to_bytes( ) function copies the null-terminated character string s to the byte array b, discarding the upper 8 bits of each 16-bit character.

The bytes_to_chars( ) function copies the null-terminated byte string b to the character array s.
