+.Sh SYNOPSIS
+.Vt char PC;
+.Vt char *BC;
+.Vt char *UP;
+.Vt short ospeed;
+.Fn tgetent "char *bp" "char *name"
+.Fn tgetnum "char *id"
+.Fn tgetflag "char *id"

+.Fn tgetstr "char *id" "char **area"
+.Ft char *
+.Fn tgoto "char *cm" destcol destline
+.Ft void
+.Fn tputs "register char *cp" "int affcnt" "int (*outc)()"
+.Sh DESCRIPTION
+These functions extract and use capabilities from a terminal capability data
+base, usually
+.Pa /usr/share/misc/termcap ,
+the format of which is described in
+.Xr termcap 5 .
+These are low level routines;
+see
+.Xr curses 3
+for a higher level package.
+.Pp
+The
+.Fn tgetent
+function
+extracts the entry for terminal
+.Fa name
+into the buffer at
+.Fa bp .
+The
+.Fa bp
+argument
+should be a character buffer of size
+1024 and must be retained through all subsequent calls to
+.Fn tgetnum ,
+.Fn tgetflag ,
+and
+.Fn tgetstr .
+The
+.Fn tgetent
+function
+returns \-1 if none of the
+.Nm termcap
+data base files could be opened,
+0 if the terminal name given does not have an entry,
+and 1 if all goes well.
+It will look in the environment for a
+.Ev TERMCAP
+variable.
+If found, and the value does not begin with a slash,
+and the terminal type
+.Fa name
+is the same as the environment string
+.Ev TERM ,
+the
+.Ev TERMCAP
+string is used instead of reading a
+.Nm termcap
+file.
+If it does begin with a slash, the string is used as a path name
+of the
+.Nm termcap
+file to search.
+If
+.Ev TERMCAP
+does not begin with a slash and
+.Fa name
+is different from
+.Ev TERM ,
+.Fn tgetent
+searches the files
+.Pa $HOME/.termcap
+and
+.Pa /usr/share/misc/termcap ,
+in that order, unless the environment variable
+.Ev TERMPATH
+exists,
+in which case it specifies a list of file pathnames
+(separated by spaces or colons) to be searched instead.
+Whenever multiple files are searched and a
+.Sy tc
+field occurs in the requested entry, the entry it names must be found
+in the same file or one of the succeeding files.
+This can speed up entry into programs that call
+.Fn tgetent ,
+as well as help debug new terminal descriptions
+or make one for your terminal if you can't write the file
+.Pa /usr/share/misc/termcap .
+.Pp
+The
+.Fn tgetnum
+function
+gets the numeric value of capability
+.Fa id ,
+returning \-1 if it is not given for the terminal.
+The
+.Fn tgetflag
+function
+returns 1 if the specified capability is present in
+the terminal's entry, 0 if it is not.
+The
+.Fn tgetstr
+function
+returns the string value of the capability
+.Fa id ,
+places it in the buffer at
+.Fa area ,
+and advances the
+.Fa area
+pointer.
+It decodes the abbreviations for this field described in
+.Xr termcap 5 ,
+except for cursor addressing and padding information.
+The
+.Fn tgetstr
+function
+returns
+.Dv NULL
+if the capability was not found.
+.Pp
+The
+.Fn tgoto
+function
+returns a cursor addressing string decoded from
+.Fa cm
+to go to column
+.Fa destcol
+in line
+.Fa destline .
+It uses the external variables
+.Va UP
+(from the
+.Sy up
+capability)
+and
+.Va BC
+(if
+.Sy bc
+is given rather than
+.Sy bs )
+if necessary to avoid placing
+.Sy \en ,
+.Sy ^D
+or
+.Sy ^@
+in
+the returned string.
+(Programs which call
+.Fn tgoto
+should be sure to turn off the
+.Dv XTABS
+bit(s),
+since
+.Fn tgoto
+may now output a tab.
+Note that programs using termcap should in general turn off
+.Dv XTABS
+anyway since some terminals use control-I for other functions,
+such as nondestructive space.)
+If a
+.Sy %
+sequence is given which is not understood, then
+.Fn tgoto
+returns
+.Pq Dv OOPS .
+.Pp
+The
+.Fn tputs
+function
+decodes the leading padding information of the string
+.Fa cp ;
+.Fa affcnt
+gives the number of lines affected by the operation, or 1 if this is
+not applicable,
+.Fa outc
+is a routine which is called with each character in turn.
+The external variable
+.Va ospeed
+should contain the output speed of the terminal as encoded by
+.Xr stty 3 .
+The external variable
+.Va PC
+should contain a pad character to be used (from the
+.SY pc
+capability)
+if a null
+.Pq Sy ^@
+is inappropriate.
