This file contains the profiling data that will be interpreted by gprof . Invoking gprof produces a report on standard output. An example is shown on the next pages. Not only the routines in your program are listed but also the library procedures and the routines they call. They are preceded by an explanation of the column labels, followed by an index.
Library routines appear with leading underscores.
