* @input: the (possibly) base64 encoded text
|
|
* @in_len: length of @input or -1 if NUL terminated
|

* @out_len: filled with length of decoded data
|
|
* @errp: pointer to a NULL-initialized error object
|
|
*
|
|
* Attempt to decode the (possibly) base64 encoded
|
|
* text provided in @input. If the @input text may
|
|
* contain embedded NUL characters, or may not be
|
|
* NUL terminated, then @in_len must be set to the
|
|
* known size of the @input buffer.
|
|
*
|
|
* Note that embedded NULs, or lack of a NUL terminator
|
|
* are considered invalid base64 data and errors
|
|
* will be reported to this effect.
|
|
*
|
|
* If decoding is successful, the decoded data will
|
|
* be returned and @out_len set to indicate the
|
|
* number of bytes in the decoded data. The caller
|
|
* must use g_free() to free the returned data when
|
|
* it is no longer required.
|
|
*
|
|
* Returns: the decoded data or NULL
