Sun Java System Messaging Server 6 2005Q4 MTA Developer's Reference

Description

This routine is used to obtain string-valued information about the current message part. (When mtaDecodeMessage() calls either a user-supplied inspection or output routine, it provides a decode context describing the current message part being processed.)

The following table lists the values for the item call argument, and gives a description of each.

Values	Description
`MTA_DECODE_CCHARSET`	The character set specified with the `CHARSET` parameter of the part’s `Content-type:` header line. If the part lacks a `CHARSET` specification, then the value `us-ascii` will be returned.
`MTA_DECODE_CDISP`	Value of the `Content-disposition:` header line, less any optional parameters. If the part lacks a `Content-disposition:` header line, the returned value will be a zero length string.
`MTA_DECODE_CSUBTYPE`	The content subtype specified with the part’s `Content-type:` header line (for example, `plain` for `text/plain`, `gif` for `image/gif`). Defaults to `plain` when the part lacks a `Content-type:` header line.
`MTA_DECODE_CTYPE`	The major content type specified with the part’s `Content-type:` header line (for example, `text` for `text/plain`, `image` for `image/gif`). Defaults to `text` when the part lacks a `Content-type:` header line.
