Create Tracepoints<\/b><\/p>\n

\n

Tracepoints are handled as a type of breakpoint. There are two differences to note:<\/p>\n<\/blockquote>\n

    \n
  1. When a tracepoint is created in a debug session, it is not actually planted in the binary code until the user explicitly starts the tracing experiment. This means that creating\/modifying\/deleting tracepoints does not affect the program until tracing is actually started.<\/li>\n
  2. Simply creating a Tracepoint has very limited value as it won't collect any information by default. It is important to add Actions to the Tracepoint to tell it what to do. This will be explained below.<\/li>\n<\/ol>\n
