.SH DESCRIPTION
These functions extract and use capabilities from a terminal capability data
base, usually
.BR /usr/share/misc/termcap ,
the format of which is described in
.BR termcap (5).
These are low level routines;
see
.BR curses (3)
for a higher level package.
.LP
The
.BR tgetent
function
extracts the entry for terminal
.I name
into the buffer at
.IR bp .
The
.I bp
argument
should be a character buffer of size
1024 and must be retained through all subsequent calls to
.BR tgetnum ,
.BR tgetflag ,
and
.BR tgetstr .
The
.BR tgetent
function
returns \-1 if none of the
.BR 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
.BR TERMCAP
variable.
If found, and the value does not begin with a slash,
and the terminal type
.I name
is the same as the environment string
.BR TERM ,
the
.BR TERMCAP
string is used instead of reading a
.BR termcap
file.
If it does begin with a slash, the string is used as a path name
of the
.BR termcap
file to search.
If
.BR TERMCAP
does not begin with a slash and
.I name
is different from
.BR TERM ,
.BR tgetent
searches the files
.BR $HOME/.termcap
and
.BR /usr/share/misc/termcap ,
in that order, unless the environment variable
.BR 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
.B 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
.BR tgetent ,
as well as help debug new terminal descriptions
or make one for your terminal if you can't write the file
.BR /usr/share/misc/termcap .
.LP
The
.BR tgetnum
function
gets the numeric value of capability
.IR id ,
returning \-1 if it is not given for the terminal.
The
.BR tgetflag
function
returns 1 if the specified capability is present in
the terminal's entry, 0 if it is not.
The
.BR tgetstr
function
returns the string value of the capability
.IR id ,
places it in the buffer at
.IR area ,
and advances the
.I area
pointer.
It decodes the abbreviations for this field described in
.BR termcap (5),
except for cursor addressing and padding information.
The
.BR tgetstr
function
returns
.BR NULL
if the capability was not found.
.LP
The
.BR tgoto
function
returns a cursor addressing string decoded from
.I cm
to go to column
.I destcol
in line
.IR destline .
It uses the external variables
.B UP
(from the
.B up
capability)
and
.B BC
(if
.B bc
is given rather than
.BR bs )
if necessary to avoid placing
.B \en ,
.BR ^D
or
.BR ^@
in
the returned string.
(Programs which call
.BR tgoto
should be sure to turn off the
.BR XTABS
bit(s),
since
.BR tgoto
may now output a tab.
Note that programs using termcap should in general turn off
.BR XTABS
anyway since some terminals use control-I for other functions,
such as nondestructive space.)
If a
.BR %
sequence is given which is not understood, then
.BR tgoto
returns
.BR OOPS .
.LP
The
.BR tputs
function
decodes the leading padding information of the string
.IR cp ,
.I affcnt
gives the number of lines affected by the operation, or 1 if this is
not applicable,
.I outc
is a routine which is called with each character in turn.
The external variable
.IR ospeed
should contain the output speed of the terminal as encoded by
.BR stty (3).
The
.BR _set_ospeed
functions converts any (not exactly matched only) numeric speed to
.BR stty (3)
encoded speed and set
.IR ospeed
variable.
The external variable
.IR PC
should contain a pad character to be used (from the
.B pc
capability)
if a null
.B ^@
is inappropriate.
.LP
The
.BR tparm
function
instantiates the string
.I cp
with given parameters.
A pointer is returned which points to
the result of
.I cp
with the parameters applied.
If a
.B %
sequence is given which is not understood, then
.BR tparm
returns
.BR OOPS .

/* sigh... this has got to be the ugliest code I've ever written.
Trying to handle everything has its cost, I guess.
It actually isn't to hard to figure out if a given % code is supposed
to be interpeted with its termcap or terminfo meaning since almost
all terminfo codes are invalid unless something has been pushed on
the stack and termcap strings will never push things on the stack
(%p isn't used by termcap). So where we have a choice we make the
decision by wether or not somthing has been pushed on the stack.
The static variable termcap keeps track of this; it starts out set
to 1 and is incremented as each argument processed by a termcap % code,
however if something is pushed on the stack it's set to 0 and the
rest of the % codes are interpeted as terminfo % codes. Another way
of putting it is that if termcap equals one we haven't decided either
way yet, if it equals zero we're looking for terminfo codes, and if
its greater than 1 we're looking for termcap codes.
Terminfo % codes:
%% output a '%'
%[[:][-+# ][width][.precision]][doxXs]
output pop according to the printf format
%c output pop as a char
%'c' push character constant c.
%{n} push decimal constant n.
%p[1-9] push paramter [1-9]
%g[a-z] push variable [a-z]
%P[a-z] put pop in variable [a-z]
%l push the length of pop (a string)
%+ add pop to pop and push the result
%- subtract pop from pop and push the result
%* multiply pop and pop and push the result
%& bitwise and pop and pop and push the result
%| bitwise or pop and pop and push the result
%^ bitwise xor pop and pop and push the result
%~ push the bitwise not of pop
%= compare if pop and pop are equal and push the result
%> compare if pop is less than pop and push the result
%< compare if pop is greater than pop and push the result
%A logical and pop and pop and push the result
%O logical or pop and pop and push the result
%! push the logical not of pop
%? condition %t if_true [%e if_false] %;
if condtion evaulates as true then evaluate if_true,
else evaluate if_false. elseif's can be done:
%? cond %t true [%e cond2 %t true2] ... [%e condN %t trueN] [%e false] %;
%i add one to parameters 1 and 2. (ANSI)
Termcap Codes:
%% output a %
%. output parameter as a character
%d output parameter as a decimal number
%2 output parameter in printf format %02d
%3 output parameter in printf format %03d
%+x add the character x to parameter and output it as a character
(UW) %-x subtract parameter FROM the character x and output it as a char
(UW) %ax add the character x to parameter
(GNU) %a[+*-/=][cp]x
GNU arithmetic.
(UW) %sx subtract parameter FROM the character x
%>xy if parameter > character x then add character y to parameter
%B convert to BCD (parameter = (parameter/10)*16 + parameter%16)
%D Delta Data encode (parameter = parameter - 2*(paramter%16))
%i increment the first two parameters by one
%n xor the first two parameters by 0140
(GNU) %m xor the first two parameters by 0177
%r swap the first two parameters
(GNU) %b backup to previous parameter
(GNU) %f skip this parameter
Note the two definitions of %a, the GNU defintion is used if the characters
after the 'a' are valid, otherwise the UW definition is used.
