#include <stdlib.h> char *l64a(long value);
This function takes a
long argument and returns a pointer to its
radix-64 representation. Negative values are supported as well.
The resulting string can be turned back into a
long value by the
a64l function (see section a64l).
A pointer to a static buffer containing the radix-64 representation of
value. Subsequent calls will overwrite the contents of this buffer.
If value is
0L, this function returns an empty string.
The radix-64 ASCII representation is a notation whereby 32-bit integers
are represented by up to 6 ASCII characters; each character represents
a single radix-64 digit. Radix-64 refers to the fact that each digit in this
representation can take 64 different values.
long type is more than 32 bits in size, only the low-order
32 bits are used.
The characters used to represent digits are `.' (dot) for 0, `/'
for 1, `0' through `9' for 2 to 11, `A' through `Z' for
12 to 37, and `a' through `z' for 38 to 63.
Note that this is not the same encoding used by either uuencode or the MIME base64 encoding.
