XtWorkProcId id;
Arguments
app_context
Specifies the application context that identifies the application.
client_data
Specifies the argument that is to be passed to the specified procedure when it is called.
proc Specifies the procedure that is.

XtAppAddInput(3Xt) MIT X11R4 XtAppAddInput(3Xt)Name
XtAppAddInput, XtRemoveInput - register and remove an input source
Syntax
XtInputId XtAppAddInput(app_context, source, condition, proc, client_data)
XtAppContext app_context;
int source;
XtPointer condition;
XtInputCallbackProc proc;
XtPointer client_data;
void XtRemoveInput(id)
XtInputId id;
Arguments
app_context
Specifies the application context that identifies the application.
client_data
Specifies the argument that is to be passed to the specified procedure when input is available.
condition Specifies the mask that indicates a read, write, or exception condition or some operating system dependent condition.
id Specifies the ID returned from the corresponding call.
proc Specifies the procedure that is to be called when input is available.
source Specifies the source file descriptor on a UNIX-based system or other operating system dependent device specification.
Description
The function registers with the Intrinsics read routine a new source of events, which is usually file input but can also be file output.
Note that file should be loosely interpreted to mean any sink or source of data. also specifies the conditions under which the source can
generate events. When input is pending on this source, the callback procedure is called.
The legal values for the condition argument are operating-system dependent. On a UNIX-based system, the condition is some union of and The
function causes the Intrinsics read routine to stop watching for input from the input source.

We have quite a few threads about this subject. I have collected some of them and arranged them by the OS which is primarily discussed in the thread.

I'm writing a command shell, and I want to be able to detect when the user presses an arrow key (otherwise it just prints [[A, [[B, etc.). I know it's relatively easy (although somewhat more time-consuming) to detect keystrokes in noncanonical mode, but I've noticed that the bash shell detects... (4 Replies)
I'm learning off Linux (Ubuntu) right now. I want to move up to Unix, but I don't want to rush like I did when it came to Windows --> to Linux. What is the best Unix OS that fits in pretty well with Ubuntu.
In other words is there kind of an equal Linux with Unix?
Also what do I need to... (10 Replies)
I noticed my hostname is <my-full-name>s-macbook.local.
