CTERMID(3)                OpenBSD Programmer's Manual               CTERMID(3)

     ctermid - generate terminal pathname

     #include <stdio.h>

     char *
     ctermid(char *buf);

     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".

     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.

     The current implementation detects no error conditions.


     The ctermid() function conforms to IEEE Std1003.1-1988 (``POSIX'').

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