CTERMID(3) FreeBSD Library Functions Manual CTERMID(3)
NAME
ctermid - generate terminal pathname
SYNOPSIS
#include <stdio.h>
char *
ctermid(char *buf);
DESCRIPTION
The ctermid() function generates a string that, when used as a pathname,
refers to the current controlling terminal of the calling process.
If buf is a null pointer, a pointer to a static area is returned.
Otherwise, the pathname is copied into the memory referenced by buf. The
argument buf is assumed to point to an array at least L_ctermid (as
defined in the include file <stdio.h>) bytes long.
The current implementation simply generates "/dev/tty".
RETURN VALUES
The ctermid() function returns a non-null pointer, which is equal to the
buf argument if it is not NULL.
ERRORS
The current implementation detects no error conditions.
SEE ALSO

STANDARDS
The ctermid() function conforms to IEEE Std 1003.1-1988 ("POSIX.1").
