| SYNOPSIS |
| int test_bit(string str, int n) |
| |
| DESCRIPTION |
| Return 0 or 1 of bit n was set in string str. |
| |
| Each character contains 6 bits. So you can store a value |
| between 0 and 63 in one character (2^6=64). Starting character |
| is the blank " " which has the value 0. The first character in |
| the string is the one with the lowest bits (0-5). |
| |
| EXAMPLES |
| test_bit("_",5); |
| |
| Returns 1 because "_" stands for the number 63 and therefore |
| the 6th bit is set. |
| |
| test_bit(" ",3); |
| |
| Returns 0 because " " stands for 0 and no bit is set. |
