- Currently, the name of input pipe is "ptyNNNN-from-master" for cygwin process, and "ptyNNNN-to-slave" for non-cygwin process. These are not only inconsistent with output pipes but also very confusing. With this patch, these are renamed to "ptyNNNN-from-master-cyg" and "ptyNNNN-from-master" respectively. --- winsup/cygwin/fhandler_tty.cc | 2 +- winsup/cygwin/tty.cc | 4 ++-- 2 files changed, 3 insertions(+), 3 deletions(-)
