Which encoding is in use is inferred automatically by \fBtermkey\fP, and does not need to be specified explicitly. .SS Position Events The \fBTERMKEY_TYPE_POSITION\fP event type indicates a cursor position report. This is typically sent by a terminal in response to the Report Cursor Position command (\f(CWCSI ? 6 n\fP). The event bytes are opaque, but can be obtained by calling \fBtermkey_interpret_position\fP(3) passing the event structure and pointers to integers to store the result in. Note that only a DEC CPR sequence (\f(CWCSI ? R\fP) is recognised, and not the non-DEC prefixed \f(CWCSI R\fP because the latter could be interpreted as the \f(CWF3\fP function key instead. +.SS Mode Reports +The \fBTERMKEY_TYPE_MODEREPORT\fP event type indicates an ANSI or DEC mode report.

It will have been extracted from the stream, but is available to the application to inspect by calling \fBtermkey_interpret_csi\fP(3). It is important that if the application wishes to inspect this sequence it is done immediately, before any other IO operations on the \fBtermkey\fP instance (specifically, before calling \fBtermkey_waitkey\fP() or \fBtermkey_getkey\fP() again), otherwise the buffer space consumed by the sequence will be overwritten. .SH "SEE ALSO" diff --git a/man/termkey_interpret_modereport.3 b/man/termkey_interpret_modereport.3 new file mode 100644 index 0000000..d778655 --- /dev/null +++ b/man/termkey_interpret_modereport.3 @@ -0,0 +1,26 @@ +.TH TERMKEY_INTERPRET_MODEREPORT 3 +.SH NAME +termkey_interpret_modereport \- interpret opaque mode report data +.SH SYNOPSIS +.nf +.B #include +.sp +.BI "TermKeyResult termkey_interpret_modereport(TermKey *" tk ", const TermKeyKey *" key ", " +.BI " int *" initial ", int *" mode ", int *" value ); +.fi +.sp +Link with \fI-ltermkey\fP. +.SH DESCRIPTION +\fBtermkey_interpret_modereport\fP() fills in variables in the passed pointers according to the mode report event found in \fIkey\fP.
