37 .Nd "convert between a long integer and a base-64 ASCII string"
43 .Fn a64l "const char *s"
47 .Fn l64a_r "long int l" "char *buffer" "int buflen"
53 functions convert between a long integer and its base-64 ASCII string
56 The characters used to represent ``digits'' are
60 `A' - `Z' for 12 - 37, and
61 `a' - `z' for 38 - 63.
64 takes a pointer to a NUL-terminated base-64 ASCII string
67 and returns the corresponding long integer value.
70 takes a long integer value,
72 and returns a pointer to the corresponding NUL-terminated base-64
73 ASCII string representation.
76 performs a conversion identical to that of
78 and stores the resulting representation in the memory area pointed to by
82 characters including the terminating NUL character.
84 On successful completion,
86 returns the long integer value corresponding to the input string.
87 If the string pointed to by
91 returns a value of 0L.
94 returns a pointer to the base-64 ASCII string representation corresponding to
100 returns a pointer to an empty string.
102 On successful completion,
106 is of insufficient length, -1 is returned.
122 Multithreading Extension.
126 function is not reentrant.
127 The value returned by it points into a static buffer area;
130 may overwrite this buffer.
131 In multi-threaded applications,
133 should be used instead.
