| * | clean up overinclusion in files using TIOCGWINSZ | Rich Felker | 2020-08-30 | 1 | -1/+0 |
| | | | | | | now that struct winsize is available via sys/ioctl.h once again, including termios.h is not needed. | ||||
| * | add tcgetwinsize and tcsetwinsize functions, move struct winsize | Rich Felker | 2020-08-24 | 1 | -0/+1 |
| | | | | | | | | | | | | | these have been adopted for future issue of POSIX as the outcome of Austin Group issue 1151, and are simply functions performing the roles of the historical ioctls. since struct winsize is being standardized along with them, its definition is moved to the appropriate header. there is some chance this will break source files that expect struct winsize to be defined by sys/ioctl.h without including termios.h. if this happens, further changes will be needed to have sys/ioctl.h expose it too. | ||||
| * | improve error handling of ttyname_r and isatty | Benjamin Peterson | 2018-09-15 | 1 | -1/+5 |
| | | | | | | | | | | POSIX allows ttyname(_r) and isatty to return EBADF if passed file descriptor is invalid. maintainer's note: these are optional ("may fail") errors, but it's non-conforming for ttyname_r to return ENOTTY when it failed for a different reason. | ||||
| * | fix possible isatty false positives and unwanted device state changes | Rich Felker | 2015-02-23 | 1 | -3/+4 |
| | | | | | | | | | | | | | | | | | | | | | | | | the equivalent checks for newly opened stdio output streams, used to determine buffering mode, are also fixed. on most archs, the TCGETS ioctl command shares a value with SNDCTL_TMR_TIMEBASE, part of the OSS sound API which was apparently used with certain MIDI and timer devices. for file descriptors referring to such a device, TCGETS will not fail with ENOTTY as expected; it may produce a different error, or may succeed, and if it succeeds it changes the mode of the device. while it's unlikely that such devices are in use, this is in principle very harmful behavior for an operation which is supposed to do nothing but query whether the fd refers to a tty. TIOCGWINSZ, used to query logical window size for a terminal, was chosen as an alternate ioctl to perform the isatty check. it does not share a value with any other ioctl commands, and it succeeds on any tty device. this change also cleans up strace output to be less ugly and misleading. | ||||
| * | initial check-in, version 0.5.0 v0.5.0 | Rich Felker | 2011-02-12 | 1 | -0/+8 |
