HP C/iX Library Function Descriptions
a64l
a64l
Converts a base-64 ASCII string to a long integer.
Syntax
[long a64l (char s );]
Parameters
s A pointer to a null terminated base-64 ASCII string. Maximum length is 6
bytes; not counting the null terminator.
Return Values
x A long integer containing the binary value of the base-64 ASCII string.
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
The a64l function is passed a pointer to a null-terminated base-64 representation and
returns a corresponding long value. If the string pointed to by
s contains more than six
characters, a64l() uses the first six (leftmost) characters.
