Sun Studio 12: Performance Analyzer

The <Total> Function

The <Total> function is an artificial construct used to represent the program as a whole. All performance metrics, in addition to being attributed to the functions on the call stack, are attributed to the special function <Total> . The function appears at the top of the function list and its data can be used to give perspective on the data for other functions. In the Callers-Callees list, it is shown as the nominal caller of _start() in the main thread of execution of any program, and also as the nominal caller of _thread_start() for created threads. If the stack unwind was incomplete, the <Total> function can appear as the caller of <Truncated-stack>.
