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
