try is part of C exception handling... I never use it myself, but I've seen
it covered intesively in a book Jamsa's C/C++ Programmer's Bible.
Basically, try initiates an excpetion handler, and some other code
(function, child programs, etc.) can call a throw statement (and exception),
and the exception is caught by the the catch statement in the try block:

 try {
    printf ( "Some text\n" );
    throw;
    printf ( "You'll never see this text\n" );
 } catch {
    printf ( "Exception caught\n" );
 }

 It has many various uses, but I've never used them for anything that I
couldn't write much more specific code for... the only REALLY good use I can
think of is catching excpeption in child programs.
