a64l(3) Library Functions Manual a64l(3)Namea64l, l64a - convert long integer and base-64 ASCII stringSyntaxlong a64l (s) char *s; char *l64a (l) long l;DescriptionThese functions are used to maintain numbers stored in base-64 ASCII characters. This is a notation by which long integers can be repre- sented by up to six characters; each character represents a ``digit'' in a radix-64 notation. 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. The subroutine takes 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, will use the first six. The subroutine takes a long argument and returns a pointer to the corresponding base-64 representation. If the argument is 0, returns a pointer to a null string.RestrictionsThe value returned by is a pointer into a static buffer, the contents of which are overwritten by each call. a64l(3)

a64l, l64a - convert between long integer and base-64 ASCII stringSYNOPSIS

#include <stdlib.h> long a64l(const char *s); char *l64a(long l);DESCRIPTION

These functions maintain numbers stored in base-64 ASCII characters that define a notation by which 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 as follows: +-----------------------------+--------------------------------+ | Character | Digit | | . | 0 | | / | 1 | | 0-9 | 2-11 | | A-Z | 12-37 | | a-z | 38-63 | +-----------------------------+--------------------------------+ The a64l() function takes 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. The a64l() function scans the character string from left to right with the least significant digit on the left, decoding each character as a 6-bit radix-64 number. The l64a() function takes a long argument and returns a pointer to the corresponding base-64 representation. If the argument is 0, 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. In the case of multi- threaded applications, the return value is a pointer to thread specific data.ATTRIBUTES
