It could be done w/o system() by using terminal control ops similar to the following: { struct termios tio; if (0 > tcgetattr(fd, *tio)) return -1; tio.c_lflag |= ICANON | ECHO; tio.c_cc[VMIN] = 1; if (0 < tcsetattr(fd, TCSANOW, ,&tio)) return -1; return 0; } where fd is the file descriptor associated with pts_name. There are a few other wrinkles that might be relevant, but they'd depend on what else is going on. -- http://sourceware.org/bugzilla/show_bug.cgi?id=3928 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ^ permalink raw reply [flat|nested] 3+ messages in thread
