Deposit(4) Document and Media Exchange Message Sets Deposit(4)NAMEDeposit - save a document to its backing store
SYNOPSIS
[file] Deposit(in mediaType contents
[in messageID commission]);
DESCRIPTION
The Deposit request saves a document to its backing store. This
request is different from the Save request in that the requester (not
the handler) has the data to be saved.
The contents argument is the contents of the document. If this argu‐
ment is unset (in other words, has a value of (char *)0), then the con‐
tents of the document are in the file named in the message's file
attribute. The data type (mediaType) of the contents argument should
be string, unless nulls are valid in the given media type, in which
case the data type must be bytes.
The commission argument contains the message ID of the Edit request
that caused the creation of this buffer.
APPLICATION USAGE
The ttmedia_load(3) function can be used to register for, and help
process, this message.
This message can be sent with the ttmedia_Deposit(3) function.
The Deposit request is useful for cases where the user may perform an
intermediate save of modifications to a document that is the subject of
an Edit or Display request in progress. In the latter case, the
Deposit may fail on a TT_DESKTOP_EACCES error if the handler does not
allow updates to the document being displayed.
Handlers receiving this request should reply before deleting any file
named in the message's file attribute, but this is optional and appli‐
cations should not rely on this.
ERRORS
The ToolTalk service may return one of the following errors in process‐
ing the Deposit request:
TT_DESKTOP_EACCES
The document is read-only.
TT_DESKTOP_ENOENT
The file that was alleged to contain the document does not
exist.
TT_DESKTOP_ENODATA
The in-mode contents argument had no value and the file
attribute of the message was not set.
TT_MEDIA_ERR_FORMAT
The document is not a valid instance of the media type.
