| SYNOPSIS |
| string xor_bits(string str1, string str2) |
| |
| DESCRIPTION |
| <str1> and <str2> are both bitstrings. The result of the function |
| is a bitstring with the binary-xor of <str1> and <str2>, |
| ie. a string in which a bit is set only if the corresponding |
| bits in either <str1> or <str2> (but not both) is set. |
| |
| EXAMPLES |
| string s1, s2, s3; |
| |
| s1 = set_bit("", 3); s1 = set_bit(s1, 15); -> s1 is "( (" |
| s2 = set_bit("", 3); s2 = set_bit(s2, 4); -> s2 is "8" |
| |
| s3 = xor_bits(s1, s2); |
| |
| -> s3 is now "0 (", ie. a bitstring with bits 4 and 15 set. |
