+ * Both *tmask* and *fmask* are byte arrays of size *tsize* and *fsize*
+ * respectively.
+ * They are located within a larger buffer at offsets *toffset* and *foffset*
+ * respectivelly. Both *tmask* and *fmask* represent bitmasks for the larger
+ * buffer.
+ * Question: are the two masks equivalent?
+ *
+ * Notes:
+ * 1. Offset basically indicates that the first offset bytes in the buffer
+ * are "don't care", so offset is equivalent to pre-pending an "all-zeros"
+ * array of *offset* bytes to the *mask*.
+ * 2. Each *mask* might contain a number of zero bytes at the beginning or
+ * at the end.
+ * 3. Bytes in the larger buffer after the end of the *mask* are also considered
+ * "don't care", so they are equivalent to appending an "all-zeros" array of
+ * bytes to the *mask*.
+ *
+ * Example:
+ * Buffer = [xx xx xx xx xx xx xx xx], buffer size = 8 bytes
+ * tmask = [00 22 00 33 00], toffset = 2, tsize = 5
+ * => buffer mask = [00 00 00 22 00 33 00 00]
+ * fmask = [22 00 33], foffset = 3, fsize = 3 =>
+ * => buffer mask = [00 00 00 22 00 33 00 00]
+ * Therefore, the tmask and fmask from this example are equivalent.
