HP C/iX Library Function Descriptions
l64a
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:
The leftmost character is the least significant digit. For example:
a0 = (38 x 64
0
) + (2 x 64
1
) = 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.
