From: Will Renkel on 24 Dec 2009 16:34 I have a need under CYGWIN to have a break(ctrl-C) handler identical to vanilla UNIX. Currently under CYGWIN, the break sequence does NOT seem to clear type ahead commands. Hence a sequence such as sleep 15; hhh;jjj ... BREAK terminates the sleep but then executes hhh and jjj. I can program a trap handler to clear the type ahead using 'tcflush(0, TCIFLUSH)'. But then I don't get correct handling of such things as unbalanced quotes on the input line. Hence input of -> 'abc <- will not terminate with a BREAK until I enter a single quote. So what I am looking for is a way to use the tcflush with the standard system capability. Any ideas for a solution? I asked this question under cygwin group but am adding it here as well. Like, how do I use the system handling AND add to it in the trap handler? -- --------------------------------------------------------------- Will Renkel Wheaton, Ill. --------------------------------------------------------------- |
