Description

Note

This reference page was automatically generated from functions found in the header files in the development branch. The function described here may not exist in generally available versions of Momentum, and may change in behavior when it is generally available. Consult your vendor for definitive advice on the use of this function.

Prepare to extract a message part in a streaming fashion.

Parameters

part

the message part to be extracted

pathway

the pathway message came in on.

desired_charset

the character set to use for textual parts.

If desired_charset is NULL, then no decoding will be performed; the stream will simply return the message part as it appears in the body.

If desired_charset is "/transfer-decode-only/" then only transfer decoding will be performed; the stream will supply the octets after decoding the transfer-encoding for that part.

Return Values

Returns an io_object that will produce the decoded part when read.

While the io_object returned from this function is active, you should not perform operations on the message that might seek the io object that underpins the message, otherwise you will confuse the extractor or vice versa.

**Configuration Change. ** This feature is available starting from Momentum 3.0.18.
