Decode an UU-encoded string
uudecode( dest[], const source[], maxlength=sizeof dest )
Since the UU-encoding scheme is for binary data, the decoded data is always “packed”. The data is unlikely to be a string (the zero-terminator may not be present, or it may be in the middle of the data).
A buffer may be decoded “in-place”; the destination size is always smaller than the source size. Endian issues (for multi-byte values in the data stream) are not handled.
Binary data is encoded in chunks of 45 bytes. To assemble these chunks into a complete stream, function memcpy allows you to concatenate buffers at bytealigned boundaries
NOTE: This is a rarely needed command for ezeio programming.
dest | The buffer that will hold the decoded data |
source | The uu-encoded source buffer |
maxlength (optional) | The size of dest in cells. If the length of dest would exceed maxlength cells, the result is truncated. |
The number of bytes stored in dest.
