uuencode

Decode an UU-encoded string

Description#

uuencode( dest[], const source[], maxlength=sizeof dest )

This function always creates a packed string. The string has a newline character at the end.

Binary data is encoded in chunks of 45 bytes. To extract 45 bytes from an array with data, possibly from a byte-aligned address, you can use the function memcpy.

A buffer may be encoded “in-place” if the destination buffer is large enough. Endian issues (for multi-byte values in the data stream) are not handled.

NOTE: This is a rarely needed command for ezeio programming.

Parameters#

`dest`	The buffer that will hold the encoded data
`source`	The plaintext 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#

Returns the number of characters encoded, excluding the zero string terminator; if the dest buffer is too small, not all bytes are stored.
