NAME

ctermid - generate terminal pathname

SYNOPSIS

Fd #include <stdio.h> Ft char * Fn ctermid char *buf

DESCRIPTION

The Fn ctermid function generates a string, that, when used as a pathname, refers to the current controlling terminal of the calling process.

If buf is the 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 Aq Pa stdio.h ) bytes long.

The current implementation simply returns `/dev/tty'

RETURN VALUES

Upon successful completion, a non- NULL pointer is returned. Otherwise, a NULL pointer is returned and the global variable errno is set to indicate the error.

ERRORS

The current implementation detects no error conditions.

STANDARDS

The ctermid function conforms to St -p1003.1-88 .

BUGS

By default the Fn ctermid function writes all information to an internal static object. Subsequent calls to Fn ctermid will modify the same object.
