I am writing an application using the X Version 11, Release 3 Toolkit
Intrinsics and Athena Widgets. Within the application I make a call to
XtAppAddInput passing a socket descriptor as the "source" argument and
XtInputReadMask as the "condition" argument. My goal is to call the
procedure passed as the "proc" argument each time data is ready to be
read from the socket, i.e. each time data is written to its connected
peer socket. The procedure itsself reads any data ready to be read from
the socket.

I ran a small test program where I wrote a single approximately 20
character long string to the peer socket. I expected the procedure
to be called once and the character string read. Upon running the
the test program, the character string was successfully read.
However, instead of proceeding on with the rest of the test program,
an infinite loop was entered with the "proc" procedure being called
over and over.

Any advice? Thanks in advance.
