Encoding.step
size_t step(string inbuf, ref char[] outbuf)Incrementally encodes or decodes (depending on state) an input stream by 'stepping' through a block of input at a time.
You should make sure outbuf is large enough by calling gmime.encoding.Encoding.outlen to find out how large outbuf might need to be.
Parameters
inbuf | an input buffer to encode or decode |
outbuf | an output buffer |
Returns
the number of bytes written to outbuf.
