.. saslman:: sasl_encode64(3)
.. _sasl-reference-manpages-library-sasl_encode64:
========================================
**sasl_encode64** - Encode base64 string
========================================
Synopsis
========
.. code-block:: C
#include <sasl/saslutil.h>
int sasl_encode64(const char * input,
unsigned inputlen,
const char ** output,
unsigned outmax,
unsigned * outputlen);
Description
===========
Use the **sasl_encode64()** interface to convert an octet string into a base64
string. This routine is useful for SASL profiles that use base64, such as the
IMAP (IMAP4) and POP (POP_AUTH) profiles. The output is null‐terminated. If
outlen is non‐NULL, the length is placed in the outlen.
.. c:function:: int sasl_encode64(const char * input,
unsigned inputlen,
const char ** output,
unsigned outmax,
unsigned * outputlen);
:param input: input data.
:param inputlen: length of the input data.
:param output: contains the decoded data. The value of out can be the
same as in. However, there must be enough space.
:param outputlen: length of `output`.
:param outmax: The maximum size of the output buffer.
Return Value
============
SASL functions should return SASL return codes.
See sasl.h for a complete list. :c:macro:`SASL_OK` indicates success.
Other return codes indicate errors and should be handled.
