uudecode

Decode an UU-encoded string

Description#

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.

Parameters#

`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.

Return value#

The number of bytes stored in dest.
