Tizen Native API 3.0
These functions allow you to add benchmark framework in a project for timing critical part and detect slow parts of code. It is used in Eina to compare the time used by eina, glib, evas and ecore data types.
To use the benchmark module, Eina must be initialized with eina_init() and later shut down with eina_shutdown(). A benchmark is created with eina_benchmark_new() and freed with eina_benchmark_free().
eina_benchmark_register() adds a test to a benchmark. That test can be run a certain amount of times. Adding more than one test to be executed allows the comparison between several parts of a program, or different implementations.
eina_benchmark_run() runs all the tests registered with eina_benchmark_register(). The amount of time of each test is written in a gnuplot file.
For more information, you can look at the Benchmark Tutorial.

bench The benchmark.
- The list of names of the test files.
This function runs all the tests that as been registered with eina_benchmark_register() and save the result in a gnuplot file. The name of the file has the following format:
Where [name] and [run] are the values passed to eina_benchmark_new().
Each registered test is executed and timed. The time is written to the gnuplot file. The number of times each test is executed is controlled by the parameters passed to eina_benchmark_register().
NULL, this functions returns
NULL immediately. Otherwise, it returns the list of the names of each test.
