hi,I want to UINT send_client_format_list(xfClipboard *clipboard)
{
WLog_DBG(TAG, "client send format list-->");
int formatsLen = 2;
CLIPRDR_FORMAT *formats = (CLIPRDR_FORMAT *)calloc(formatsLen, sizeof(CLIPRDR_FORMAT));
formats[0].formatId = CF_RAW;
formats[0].formatName = _strdup("RAW");
formats[1].formatId = CF_UNICODETEXT;
formats[1].formatName = _strdup("UTF8_STRING");
const CLIPRDR_FORMAT_LIST formatList = {.common.msgFlags = CB_RESPONSE_OK,
.numFormats = formatsLen,
.formats = formats,
.common.msgType = CB_FORMAT_LIST};
/* Ensure all pending requests are answered. */
xf_cliprdr_send_data_response(clipboard, NULL, 0);
for (int i = 0; i < formatList.numFormats; i++)
{
WLog_DBG(TAG, "client format list id:%d name:%s", formatList.formats[i].formatId, formatList.formats[i].formatName);
}
WINPR_ASSERT(clipboard->context);
WINPR_ASSERT(clipboard->context->ClientFormatList);
return clipboard->context->ClientFormatList(clipboard->context, &formatList);
}
void clipboard_init(xfContext *xfc, CliprdrClientContext *cliprdr)
{
WINPR_ASSERT(xfc);
WINPR_ASSERT(cliprdr);
xfc->cliprdr = cliprdr;
xfc->clipboard->context = cliprdr;
cliprdr->custom = (void *)xfc->clipboard;
/*https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-rdpeclip/fb9b7e0b-6db4-41c2-b83c-f889c1ee7688*/
/*init handlers*/
cliprdr->ServerCapabilities = server_clipboard_capabilities;
cliprdr->MonitorReady = server_monitor_ready;
cliprdr->ServerFormatListResponse = server_format_list_response;
/*data transfer sequences*/
cliprdr->ServerFormatDataRequest = server_format_data_request;
}Is there any reason for this problem? thanks a lot. UPDATE: UINT send_client_format_list(xfClipboard *clipboard)
{
WLog_DBG(TAG, "client send format list-->");
int numFormats = clipboard->numClientFormats;
CLIPRDR_FORMAT *formats = NULL;
if (numFormats)
{
if (!(formats = (CLIPRDR_FORMAT *)calloc(numFormats, sizeof(CLIPRDR_FORMAT))))
{
WLog_ERR(TAG, "failed to allocate %" PRIu32 " CLIPRDR_FORMAT structs", numFormats);
return CHANNEL_RC_NO_MEMORY;
}
}
for (int i = 0; i < numFormats; i++)
{
const xfCliprdrFormat *clientFormat = &clipboard->clientFormats[i];
CLIPRDR_FORMAT *format = &formats[i];
format->formatId = clientFormat->formatId;
format->formatName = clientFormat->formatName;
}
const CLIPRDR_FORMAT_LIST formatList = {.common.msgFlags = CB_RESPONSE_OK,
.numFormats = numFormats,
.formats = formats,
.common.msgType = CB_FORMAT_LIST};
/* Ensure all pending requests are answered. */
xf_cliprdr_send_data_response(clipboard, NULL, 0);

you need to check your check [MS-DCLB] for details about formats to send |

thank you,I do not specify this unicode format There is one more question that I have,when server format data request triggered the first time,I send unicode string to the rdp server(Local) in Thank you for your answer! xfClipboard *clipboard_new(xfContext *xfc)
{
rdpChannels *channels;
xfClipboard *clipboard;
xfCliprdrFormat *clientFormat;
int n;
WINPR_ASSERT(xfc);
WINPR_ASSERT(xfc->common.context.settings);
if (!(clipboard = (xfClipboard *)calloc(1, sizeof(xfClipboard))))
{
WLog_ERR(TAG, "failed to allocate xfClipboard data");
return NULL;
}
xfc->clipboard = clipboard;
clipboard->xfc = xfc;
channels = xfc->common.context.channels;
clipboard->channels = channels;
clipboard->system = ClipboardCreate();
clipboard->requestedFormatId = -1;
clientFormat = &clipboard->clientFormats[n++];
clientFormat->formatId = CF_RAW;
clientFormat = &clipboard->clientFormats[n++];
clientFormat->formatId = CF_UNICODETEXT;
clipboard->numClientFormats = n;
clipboard->delegate = ClipboardGetDelegate(clipboard->system);
clipboard->delegate->custom = clipboard;
return clipboard;

you need to check your
formatNamestuff. e.g.UTF8_STRINGis an identifier from your localX11clipboard, so you sent the wrong data over the RDP clipboard APIcheck [MS-DCLB] for details about formats to send
