TTYNAME(3) Linux Programmer's Manual TTYNAME(3)NAME
ttyname, ttyname_r - return name of a terminal
SYNOPSIS
#include <unistd.h>
char *ttyname(int desc);
int ttyname_r(int desc, char *buf, size_t buflen);
DESCRIPTION
The function ttyname() returns a pointer to the NUL-terminated pathname of the terminal device that is open on the file descriptor desc, or
NULL on error (for example, if desc is not connected to a terminal). The return value may point to static data, possibly overwritten by
the next call. The function ttyname_r() stores this pathname in the buffer buf of length buflen.
RETURN VALUE
The function ttyname() returns a pointer to a pathname on success. On error, NULL is returned, and errno is set appropriately. The func-
tion ttyname_r() returns 0 on success, and an error number upon error.
ERRORS
Values stored in errno by a failing ttyname() or returned by a failing ttyname_r():
EBADF Bad file descriptor.
ENOTTY File descriptor does not refer to a terminal device.
ERANGE buflen was too small to allow storing the pathname.
CONFORMING TO
POSIX.1

ttyname, ttyname_r - return name of a terminal
SYNOPSIS
#include <unistd.h>
char *ttyname(int fd);
int ttyname_r(int fd, char *buf, size_t buflen);
DESCRIPTION
The function ttyname() returns a pointer to the null-terminated pathname of the terminal device that is open on the file descriptor fd, or
NULL on error (for example, if fd is not connected to a terminal). The return value may point to static data, possibly overwritten by the
next call. The function ttyname_r() stores this pathname in the buffer buf of length buflen.
RETURN VALUE
The function ttyname() returns a pointer to a pathname on success. On error, NULL is returned, and errno is set appropriately. The func-
tion ttyname_r() returns 0 on success, and an error number upon error.
ERRORS
ttyname_r():
EBADF Bad file descriptor.
ENOTTY File descriptor does not refer to a terminal device.
ERANGE buflen was too small to allow storing the pathname.

Hi folks. I know this is going to be one of those ones where I just need to stick a bracket or a single quote somewhere to fix, but it's killing me to try and work out why it's failing.
