     27 * qbase64_decode:
     28 * @input: the (possibly) base64 encoded text
     29 * @in_len: length of @input or -1 if NUL terminated
     30 * @out_len: filled with length of decoded data
     31 * @errp: pointer to a NULL-initialized error object
     32 *
     33 * Attempt to decode the (possibly) base64 encoded
     34 * text provided in @input. If the @input text may
     35 * contain embedded NUL characters, or may not be
     36 * NUL terminated, then @in_len must be set to the
     37 * known size of the @input buffer.
     38 *
     39 * Note that embedded NULs, or lack of a NUL terminator
     40 * are considered invalid base64 data and errors
     41 * will be reported to this effect.
     42 *
     43 * If decoding is successful, the decoded data will
     44 * be returned and @out_len set to indicate the
     45 * number of bytes in the decoded data. The caller
     46 * must use g_free() to free the returned data when
     47 * it is no longer required.
     48 *
     49 * Returns: the decoded data or NULL
