.SH "DESCRIPTION"

.PP

\fBXmClipboardRetrieve\fP retrieves the current data item from clipboard

storage\&. It returns a warning if the clipboard is locked, if there is

no data on the clipboard, or if the data needs to be truncated because the

buffer length is too short\&.

.PP

Between a call

to \fBXmClipboardStartRetrieve\fP and a call to \fBXmClipboardEndRetrieve\fP,

multiple calls to \fBXmClipboardRetrieve\fP

with the same format name result

in data being incrementally copied from the clipboard until the data in that

format has all been copied\&.

.PP

The return value \fBXmClipboardTruncate\fP from calls to

\fBXmClipboardRetrieve\fP indicates that more data remains to be copied in the

given format\&.

It is recommended that any calls to the \fBInquire\fP functions that

the application needs to make to effect the copy from the clipboard be

made between the call to \fBXmClipboardStartRetrieve\fP and the first

call to \fBXmClipboardRetrieve\fP\&. This way, the application does not

need to call \fBXmClipboardLock\fP and \fBXmClipboardUnlock\fP\&.

.IP "\fIdisplay\fP" 10

Specifies a pointer to the \fBDisplay\fR structure that was returned in a

previous call to \fBXOpenDisplay\fP or \fBXtDisplay\fP\&.

.IP "\fIwindow\fP" 10

Specifies the window ID of a widget that relates the application window to the

clipboard\&. The widget\&'s window ID can be obtained through

\fBXtWindow\fP\&.

The same application instance should pass the same window ID to each of the

clipboard functions that it calls\&.

.IP "\fIformat_name\fP" 10

Specifies the name of a format in which the data

is stored on the clipboard\&.

.IP "\fIbuffer\fP" 10

Specifies the buffer to which the application wants the

clipboard to copy the data\&.

The function allocates space to hold the data returned into the buffer\&.

The application is responsible for managing this allocated space\&.

The application can recover this allocated space by calling \fBXtFree\fP\&.

.IP "\fIlength\fP" 10

Specifies the length of the application buffer\&.

.IP "\fInum_bytes\fP" 10

Specifies the number of bytes of data copied into the application

buffer\&.

.IP "\fIprivate_id\fP" 10

Specifies the private data stored with the data item by the

application that placed the data item on the clipboard\&. If the

application did not store private data with the data item, this

argument returns 0 (zero)\&.

.SH "RETURN"

.IP "\fBXmClipboardSuccess\fP" 10

The function was successful\&.

.IP "\fBXmClipboardLocked\fP" 10

The function failed because the clipboard was locked by another

application\&. The application can continue to call the function again with

the same parameters until the lock goes away\&. This gives the application

the opportunity to ask if the user wants to keep trying or to give up

on the operation\&.

.IP "\fBXmClipboardTruncate\fP" 10

The data returned is truncated because the user did not provide a buffer

large enough to hold the data\&.

.IP "\fBXmClipboardNoData\fP" 10

The function could not find data on the clipboard corresponding to the

format requested\&. This could occur because the clipboard is empty;

there is data on the clipboard but not in the requested format; or the

data in the requested format was passed by name and is no longer

available\&.
