# sasl_decode64 - Decode base64 string

## Synopsis

    #include <sasl/saslutil.h>

    int sasl_decode64(const char * input,
                    unsigned inputlen,
                   char * output,
                   unsigned outmax,
                   unsigned * outputlen);

## Description

int sasl_decode64(const char * input,
unsigned inputlen,
const char ** output,
unasigned outmax,
unsigned * outputlen);

  sasl_decode64 decodes a base64 encoded buffer.

  Parameters:

    - input – Input data.

    - inputlen – The length of the input data.

    - output – contains the decoded data. The value of output can be the same as in. However, there must be enough space.

    - outmax – The maximum size of the output buffer.

    - outputlen – length of output.

## Return Value

SASL callback functions should return SASL return codes. See sasl.h for a complete list. `SASL_OK` indicates success.

Other return codes indicate errors and should be handled.
