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. -.PP -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. -.PP -The \fBtgetflag\fR routine gets the boolean entry for \fIid\fR, -or zero if it is not available. -.PP -The \fBtgetnum\fR routine gets the numeric entry for \fIid\fR, -or -1 if it is not available. -.PP -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 return value will also be copied to the buffer pointed to by \fIarea\fR, -and the \fIarea\fR value will be updated to point past the null ending -this value. -.PP -Only the first two characters of the \fBid\fR parameter of -\fBtgetflag\fR, -\fBtgetnum\fR and -\fBtgetstr\fR are compared in lookups. -.PP -The \fBtgoto\fR routine instantiates the parameters into the given capability. -The output from this routine is to be passed to \fBtputs\fR. -.PP -The \fBtputs\fR routine is described on the \fBcurs_terminfo\fR(3X) manual -page. It can retrieve capabilities by either termcap or terminfo name. -.PP -The variables -\fBPC\fR, -\fBUP\fR and -\fBBC\fR -are set by \fBtgetent\fR to the terminfo entry's data for -\fBpad_char\fR, -\fBcursor_up\fR and -\fBbackspace_if_not_bs\fR, -respectively. -\fBUP\fR is not used by ncurses. -\fBPC\fR is used in the \fBtdelay_output\fR function. -\fBBC\fR is used in the \fBtgoto\fR emulation. -The variable \fBospeed\fR is set by ncurses in a system-specific coding -to reflect the terminal speed. -. -.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. -.PP -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 will not cause problems if all -you do with it is call \fBtgoto\fR or \fBtparm\fR, which both expand -terminfo-style strings as terminfo. -(The \fBtgoto\fR function, if configured to support termcap, will check -if the string is indeed terminfo-style by looking for "%p" parameters or -"$<..>" delays, and invoke a termcap-style parser if the string does not -appear to be terminfo). -.PP -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. -.PP -Note that termcap has nothing analogous to terminfo's \fBsgr\fR string. -One consequence of this is that termcap applications assume \fRme\fR -(terminfo \fBsgr0\fR) does not reset the alternate character set. -This implementation checks for, and modifies the data shown to the -termcap interface to accommodate termcap's limitation in this respect. -.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. -.PP -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. -In particular, an omission in the XSI Curses documentation has been -misinterpreted to mean that \fBtgetent\fR returns \fBOK\fR or \fBERR\fR. -Because the purpose of these functions is to provide compatibility with -the \fItermcap\fR library, that is a defect in XCurses, Issue 4, Version 2 -rather than in ncurses. -.PP -External variables are provided for support of certain termcap applications. -However, termcap applications' use of those variables is poorly documented, -e.g., not distinguishing between input and output. -In particular, some applications are reported to declare and/or -modify \fBospeed\fR. -.SH SEE ALSO -\fBcurses\fR(3X), \fBterminfo\fR(\*n), \fBputc\fR(3). -.\"# -.\"# The following sets edit modes for GNU EMACS -.\"# Local Variables: -.\"# mode:nroff -.\"# fill-column:79 -.\"# End: |
