NAME
ttyname(), ttyname_r(), isatty() - find name of a terminal SYNOPSIS
DESCRIPTION
returns a pointer to a string containing the null-terminated path name of the terminal device associated with file descriptor fildes. returns 1 if fildes is associated with a terminal device, 0 otherwise. Reentrant Interfaces returns the result string in the supplied buffer. The buffer is buflen characters long and should have space for the name and the terminat- ing null character. The maximum length of the terminal name is RETURN VALUE
returns a NULL pointer if fildes does not describe a terminal device in directory returns a zero upon success and an error number upon failure. ERRORS
and fail if any of the following conditions are encountered: The fildes argument is invalid. An inappropriate I/O control operation has been attempted. APPLICATION USAGE
The return value for points to static data whose content is overwritten by each call. WARNINGS
For streams ptys, and do not consider master ptys to be tty devices. It should also be noted that returns a pointer to the master pty name for all master pty devices. This is a result of device files being linked together. Users of should also note that the prototype of this function has changed in this release for conformance with the POSIX.1c Threads stan- dard. The old prototype of is supported for compatibility with existing DCE applications only. FILES
