Locking mintty terminal, possible? #347

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Using pv can't lock terminal. Examples:

dd if=/dev/urandom of=random.data bs=20M count=1
pv -cN source random.data | gzip | pv -cN gzip > random.data.gz

Detailed here:

There are compiled versions of pv on the internet.

Looking at the pv source code, apparently it's this call this fails:

  fcntl(fd, F_SETLKW, &lock);

This indicates that the Cygwin DLL doesn't support file locking on terminal 
devices. The fact that it's the same in rxvt confirms that it isn't a 
mintty-specific issue. Please take this to the Cygwin mailing list.
