Decoder inline | ||
ssize_t | decode inline | Decodes a single Base64 character to its 6-bit value. |
ssize_t | decode virtual inline override | Decodes a raw Base64 buffer into binary data. |
void | decode inline | Decodes the entire input stream and writes binary output to ostrm. Resets the decoder state after completion. |
