NAME

     tgetent, tgetnum, tgetflag, tgetstr, tgoto, tputs -- terminal independent operation routines

LIBRARY

     Termcap Access Library (libtermcap, -ltermcap)

SYNOPSIS

     #include <termcap.h>

     char PC;
     char *BC;
     char *UP;

     int
     tgetent(char *bp, const char *name);

     int
     tgetnum(const char *id);

     int
     tgetflag(const char *id);

     char *
     tgetstr(const char *id, char **area);

     char *
     tgoto(const char *cm, int destcol, int destline);

DESCRIPTION

     These functions extract and use capabilities from a terminal capability database.	They exist as wrappers around equivalent terminfo(3) func-
     tions, which new code should use.	These are low level routines; see curses(3) for a higher level package.

     The tgetent() function calls setupterm() and configures PC, UP and BC.  Only PC is actually used internally.  The tgetent() function returns
     -1 if none of the terminfo data base files could be opened, 0 if the terminal name given does not match an entry, and 1 if all goes well.
     The bp argument is not used.

     The tgetnum() function gets the numeric value of the capability id, returning -1 if it is not given for the terminal.  The tgetflag() func-
     tion returns 1 if the specified capability is present in the terminal's entry, 0 if it is not.  The tgetstr() function returns the string
     value of the capability id.  This is a terminfo(5) string and not a termcap string; as such it should only be processed by tgoto().  The
     tgetstr() function returns NULL if the capability was not found.  The area argument is unused.

     The tgoto() function returns a cursor addressing string decoded from cm to go to column destcol in line destline, or NULL on error conditions
     such as out of memory.  Please note that tgoto() can return an incomplete value on a malformed input sequence.  Historically tgoto() used to
     return ``OOPS'' on those conditions, so newer programs should now be checking the return value.

HISTORY

     termcap first appeared in 4.0BSD.	NetBSD 1.5 introduced some termcap t_*() extensions which were removed in NetBSD 6.0 when terminfo(3) was
     introduced.
