GETTTYENT(3)						     Library Functions Manual						      GETTTYENT(3)

NAME

       getttyent, getttynam, setttyent, endttyent - get ttys file entry

SYNOPSIS

       #include <ttyent.h>

       struct ttyent *getttyent(void);

       struct ttyent *getttynam(const char *name);

       int setttyent(void);

       int endttyent(void);

DESCRIPTION

       These functions provide an interface to the file _PATH_TTYS (e.g., /etc/ttys).

       The function setttyent() opens the file or rewinds it if already open.

       The function endttyent() closes the file.

       The function getttynam() searches for a given ttyname in the file. It returns a pointer to a struct ttyent (description below).

       The  function  getttyent()  opens  the  file  _PATH_TTYS (if necessary) and returns the first entry.  If the file is already open, the next
       entry.

   The ttyent structure
       struct ttyent {
	       char    *ty_name;       /* terminal device name */
	       char    *ty_getty;      /* command to execute, usually getty */
	       char    *ty_type;       /* terminal type for termcap */
	       int     ty_status;      /* status flags */
	       char    *ty_window;     /* command to start up window manager */
	       char    *ty_comment;    /* comment field */
       };

       ty_status can be
       #define TTY_ON	    0x01   /* enable logins (start ty_getty program) */
       #define TTY_SECURE   0x02   /* allow uid 0 to login */

NOTES

       Under Linux the file /etc/ttys, and the functions described above, are not used.

NAME

       getttyent, getttynam, setttyent, endttyent - get ttys file entry

SYNOPSIS

       #include <ttyent.h>

       struct ttyent *getttyent(void);

       struct ttyent *getttynam(const char *name);

       int setttyent(void);

       int endttyent(void);

DESCRIPTION

       These functions provide an interface to the file _PATH_TTYS (e.g., /etc/ttys).

       The function setttyent() opens the file or rewinds it if already open.

       The function endttyent() closes the file.

       The function getttynam() searches for a given ttyname in the file.  It returns a pointer to a ttyent structure (description below).

       The  function  getttyent()  opens  the  file  _PATH_TTYS (if necessary) and returns the first entry.  If the file is already open, the next
       entry.  The ttyent structure has the form:

	   struct ttyent {
	       char *ty_name;	  /* terminal device name */
	       char *ty_getty;	  /* command to execute, usually getty */
	       char *ty_type;	  /* terminal type for termcap */
	       int   ty_status;   /* status flags */
	       char *ty_window;   /* command to start up window manager */
	       char *ty_comment;  /* comment field */
	   };

       ty_status can be:

       #define TTY_ON	  0x01	/* enable logins (start ty_getty program) */
       #define TTY_SECURE 0x02	/* allow UID 0 to login */

CONFORMING TO

       Not in POSIX.1-2001.  Present on the BSDs, and perhaps other systems.

NOTES

       Under Linux the file /etc/ttys, and the functions described above, are not used.
