This API allows for basic profiling information to be printed out over console.
|
||
|
|
|
||
|
|
Usage example:
|
||
|
|
|
||
|
|
#include "basic_profiling.h"
|
||
|
|
|
||
|
|
// Original code:
|
||
|
|
matrix_task();
|
||
|
|
|
||
|
|
// Delete the original, replace with the following (variant 1, automatic naming):
|
||
|
|
PROFILE_CALL(1000, matrix_task());
|
||
|
|
|
||
|
|
// Delete the original, replace with the following (variant 2, explicit naming):
|
||
|
|
PROFILE_CALL_NAMED(1000, "matrix_task", {
|
||
|
|
matrix_task();
|
||
|
|
});
