Converts between long integers and base-64 ASCII strings.
Standard C Library (libc.a)
long a64l ( String)
char *l64a ( LongInteger )
The a64l and l64a subroutines maintain numbers stored in base-64 ASCII characters. This is a notation in which long integers are represented by up to 6 characters, each character representing a digit in a base-64 notation.
The following characters are used
to represent digits:
|0 -9||Represents the numbers 2-11.|
|A-Z||Represents the numbers 12-37.|
|a-z||Represents the numbers 38-63.|
|String||Specifies the address of a null-terminated character string.|
|LongInteger||Specifies a long value to convert.|
The a64l subroutine takes a pointer to a null-terminated character string containing a value in base-64 representation and returns the corresponding long value. If the string pointed to by the String parameter contains more than 6 characters, the a64l subroutine uses only the first 6.
Conversely, the l64a subroutine takes a long parameter and returns a pointer to the corresponding base-64 representation. If the LongInteger parameter is a value of 0, the l64a subroutine returns a pointer to a null string.
The value returned by the l64a subroutine is a pointer into a static buffer, the contents of which are overwritten by each call.
If the *String parameter is a null string, the a64l subroutine returns a value of 0L.
If LongInteger is 0L, the l64a subroutine returns a pointer to a null string.
These a64l and l64a subroutines are part of Base Operating System (BOS) Runtime.
