+.Nm a64l ,

+.Sh SYNOPSIS
+.Fd #include <stdlib.h>
+.Ft long
+.Fn a64l "const char *s"
+.Ft char *
+.Fn l64a "long l"
+.Sh DESCRIPTION
+The
+.Fn a64l
+and
+.Fn l64a
+functions are used to maintain numbers stored in radix-64
+ASCII characters.  This is a notation by which 32-bit integers
+can be represented by up to six characters; each character
+represents a "digit" in a radix-64 notation.
+.Pp
+The characters used to represent "digits" are '.' for 0, '/' for 1,
+'0' through '9' for 2-11, 'A' through 'Z' for 12-37, and 'a' through
+'z' for 38-63.
+.Pp
+The
+.Fn a64l
+function takes a pointer to a null-terminated radix-64 representation
+and returns a corresponding 32-bit value.  If the string pointed to by
+.Ar s
+contains more than six characters,
+.Fn a64l
+will use the first six.
+.Fn A64l
+scans the character string from left to right, decoding
+each character as a 6-bit radix-64 number.  If a long integer is
+larger than 32 bits, the return value will be sign-extended.
+.Pp
+.Fn l64a
+takes a long integer argument
+.Ar l
+and returns a pointer to the corresponding radix-64 representation.
+.Sh RETURN VALUES
+On success,
+.Fn a64l
+returns a 32-bit representation of
+.Ar s .
+If
+.Ar s
+is a NULL pointer or if it contains "digits" other than those described above,
+.Fn a64l
+returns -1L and sets the global variable errno to
+.Va EINVAL .
+.Pp
+On success,
+.Fn l64a
+returns a pointer to a string containing the radix-64 representation of
+.Ar l .
+If
+.Ar l
+is 0,
+.Fn l64a
+returns a pointer to the empty string.
+If
+.Ar l
+is negative,
+.Fn l64a
+returns a NULL pointer and sets the global variable errno to
+.Va EINVAL .
+.Sh WARNINGS
+The value returned by
+.Fn l64a
+is a pointer into a static buffer, the contents of which
+will be overwritten by subsequent calls.
+.Pp
+The value returned by
+.Fn a64l
+may be incorrect if the value is too large; for that reason, only strings
+that resulted from a call to
+.Fn l64a
+should be used to call
+.Fn a64l .
+.Pp
+If a long integer is larger than 32 bits, only the low-order
+32 bits are used.
+.Sh STANDARDS
+The
+.Fn a64l
