+.SH NAME
+ttyname, ttyname_r \- find the pathname of a terminal
+.SH SYNOPSIS
+.LP
+\fB#include <unistd.h>
+.br
+.sp
+char *ttyname(int\fP \fIfildes\fP\fB);
+.br
+\fP
+.LP
+\fBint ttyname_r(int\fP \fIfildes\fP\fB, char *\fP\fIname\fP\fB, size_t\fP
+\fInamesize\fP\fB); \fP

+.SH DESCRIPTION
+.LP
+The \fIttyname\fP() function shall return a pointer to a string containing
+a null-terminated pathname of the terminal
+associated with file descriptor \fIfildes\fP. The return value may
+point to static data whose content is overwritten by each
+call.
+.LP
+The \fIttyname\fP() function need not be reentrant. A function that
+is not required to be reentrant is not required to be
+thread-safe.
+.LP
+The \fIttyname_r\fP() function shall store the null-terminated pathname
+of the terminal associated with the file descriptor
+\fIfildes\fP in the character array referenced by \fIname\fP. The
+array is \fInamesize\fP characters long and should have space
+for the name and the terminating null character. The maximum length
+of the terminal name shall be {TTY_NAME_MAX}. 
+.SH RETURN VALUE
+.LP
+Upon successful completion, \fIttyname\fP() shall return a pointer
+to a string. Otherwise, a null pointer shall be returned and
+\fIerrno\fP set to indicate the error.
+.LP
+If successful, the \fIttyname_r\fP() function shall return zero. Otherwise,
+an error number shall be returned to indicate the
+error. 
+.SH ERRORS
+.LP
+The \fIttyname\fP() function may fail if:
+.TP 7
+.B EBADF
+The \fIfildes\fP argument is not a valid file descriptor.
+.TP 7
+.B ENOTTY
+The \fIfildes\fP argument does not refer to a terminal.

+The \fIttyname_r\fP() function may fail if:
+.TP 7
+.B EBADF
+The \fIfildes\fP argument is not a valid file descriptor. 
+.TP 7
+.B ENOTTY
+The \fIfildes\fP argument does not refer to a terminal. 
+.TP 7
+.B ERANGE
+The value of \fInamesize\fP is smaller than the length of the string
+to be returned including the terminating null character.

+\fIThe following sections are informative.\fP
+.SH EXAMPLES
+.LP
+None.
+.SH APPLICATION USAGE
+.LP
+None.
+.SH RATIONALE
+.LP
+The term ``terminal'' is used instead of the historical term ``terminal
+device'' in order to avoid a reference to an undefined
+term.
+.LP
+The thread-safe version places the terminal name in a user-supplied
+buffer and returns a non-zero value if it fails. The
+non-thread-safe version may return the name in a static data area
+that may be overwritten by each call.
+.SH FUTURE DIRECTIONS
+.LP
+None.
