.SH DESCRIPTION
|
|
These routines are included as a conversion aid for programs that use
|
|
the \fItermcap\fR library. Their parameters are the same and the
|
|
routines are emulated using the \fIterminfo\fR database. Thus, they
|
|
can only be used to query the capabilities of entries for which a
|
|
terminfo entry has been compiled.
|
|
|
|
The \fBtgetent\fR routine loads the entry for \fIname\fR.
|
|
It returns 1 on success, 0 if there is no such entry, and -1 if the
|
|
terminfo database could not be found.
|
|
The emulation ignores the buffer pointer \fIbp\fR.
|
|
|
|
The \fBtgetflag\fR routine gets the boolean entry for \fIid\fR,
|
|
or zero if it is not available.
|
|
|
|
The \fBtgetnum\fR routine gets the numeric entry for \fIid\fR,
|
|
or -1 if it is not available.
|
|
|
|
The \fBtgetstr\fR routine returns the string entry for \fIid\fR,
|
|
or zero if it is not available.
|
|
Use \fBtputs\fR to output the returned string.
|
|
|
|
The \fBtgoto\fR routine instantiates the parameters into the given capability.
|
|
The output from this routine is to be passed to \fBtputs\fR.
|
|
|
|
The \fBtputs\fR routine is described on the \fBcurs_terminfo\fR(3X) manual
|
|
page. It can retrieve capabilities by either termcap or terminfo name.
|
|
|
|
.SH RETURN VALUE
|
|
Except where explicitly noted,
|
|
routines that return an integer return \fBERR\fR upon failure and \fBOK\fR
|
|
(SVr4 only specifies "an integer value other than \fBERR\fR") upon successful
|
|
completion.
|
|
|
|
Routines that return pointers return \fBNULL\fR on error.
|
|
.SH BUGS
|
|
If you call \fBtgetstr\fR to fetch \fBca\fR or any other parameterized string,
|
|
be aware that it will be returned in terminfo notation, not the older and
|
|
not-quite-compatible termcap notation. This won't cause problems if all
|
|
you do with it is call \fBtgoto\fR or \fBtparm\fR, which both expand
|
|
terminfo-style.
|
|
|
|
Because terminfo conventions for representing padding in string capabilities
|
|
differ from termcap's, \fBtputs("50");\fR will put out a literal "50" rather
|
|
than busy-waiting for 50 milliseconds. Cope with it.
|
|
.SH PORTABILITY
|
|
The XSI Curses standard, Issue 4 describes these functions. However, they
|
|
are marked TO BE WITHDRAWN and may be removed in future versions.
|
|
|
|
Neither the XSI Curses standard nor the SVr4 man pages documented the return
|
|
values of \fBtgetent\fR correctly, though all three were in fact returned ever
|
|
since SVr1.
