CTERMID(3) BSD Library Functions Manual CTERMID(3)NAMEctermid, ctermid_r -- generate terminal pathnameLIBRARYStandard C Library (libc, -lc)SYNOPSIS#include <stdio.h> char * ctermid(char *buf); char * ctermid_r(char *buf);DESCRIPTIONThe 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 be at least L_ctermid (as defined in the include file <stdio.h>) bytes long. The ctermid_r() function provides the same functionality as ctermid() except that if buf is a NULL pointer, NULL is returned. The current implementation simply returns '/dev/tty'.RETURN VALUESThe ctermid() function returns buf if it is non-NULL, otherwise it returns the address of a static buffer. The ctermid_r() function always returns buf, even if it is the NULL pointer.ERRORSThe current implementation detects no error conditions.SEE ALSOttyname(3)STANDARDSThe ctermid() function conforms to IEEE Std 1003.1-1988 (``POSIX.1'').BUGSBy default the ctermid() function writes all information to an internal static object. Subsequent calls to ctermid() will modify the same object.BSDOctober 1, 2011 BSD
