l64a
Converts a long integer to a base-64 ASCII string.
Syntax
char *l64a (l)
long l;
Parameters
l A long integer.
Return Values
x A pointer to the base-64 ASCII string.
NULL The argument is 0.
Description
This function maintains numbers stored in base-64 ASCII characters. Long
integers can be represented by up to six characters. Each character
represents a digit in a radix-64 notation.
The characters used to represent digits are:
-----------------------------------------------
| | |
| Characters | Digits |
| | |
-----------------------------------------------
| | |
| . | 0 |
| | |
-----------------------------------------------
| | |
| / | 1 |
| | |
-----------------------------------------------
| | |
| 0 through 9 | 2 through 11 |
| | |
-----------------------------------------------
| | |
| A through Z | 12 through 37 |
| | |
-----------------------------------------------
| | |
| a through z | 38 through 63 |
| | |
-----------------------------------------------
The leftmost character is the least significant digit. For example:
a0 = (38 x 640) + (2 x 641) = 166
This function takes a long argument and returns a pointer to the
corresponding base-64 representation. If the argument is zero, l64a
returns a pointer to a null string.
The value returned by l64a is a pointer into a static buffer, the
contents of which are overwritten by each call.
