CTERMID(3)		   BSD Programmer's 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. Other-
     wise, the pathname is copied into the memory referenced by buf. The argu-
     ment 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
     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.

SEE ALSO
     ttyname(3)

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

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