Hello, In one of my PCs, dd if=/dev/urandom count=10 | xxd > /dev/clipboard sometimes fails to set CF_UNICODETEXT data. As a result, pasting clipboard to notepad does not work.
Even in the case, cygnativeformat data is set correctly.
So, "cat /dev/clipboard" works.
This problem depends on machine very much.
My one PC with Xeon E3-1281 v3 CPU has a high probability of failure,
however, another machine with Core i7-6700K CPU does not.
I looked into this problem, and found OpenClipboard() for
CF_UNICODETEXT fails. It seems that OpenClipboard() just
after CloseClipboard() has high probability of failure.
You can see the following test case immediately stops with error.
Even with Core i7-6700K CPU machine above, the test case fails.
#include <windows.h>
#include <stdio.h>
int main()
{
for (;;) {
if (!OpenClipboard(0)) {
printf("Open error.\n");
break;
}
if (!EmptyClipboard()) {
printf("Empty error.\n");
break;
}
if (!CloseClipboard()) {
printf("Cloes error.\n");
break;
}
}
return 0;
}
I also found the patch attached solves the issue.
I would appreciate any suggestion.
