profiler

This C profiler is used to messure time during runtime. A quick example is provided here.
This profilers mesuares nanoseconds accurate. Internally the profiler is stackbased so that no comparision have to be made to determine the end of one profiler.

Features

• Nanosecond accurate measuring
• Optional thresholds for each profiler
• Filterable levels of outputs (errors, alerts and infos)

Todos

• File as output instead of console
• C++ compatible
• Windows compatible

Dependencies

None.

Quick example

C file

// Define PROFILER_IMPLEMENTATION if it is not defined anywhere else in your project.
#define PROFILER_IMPLEMENTATION
// Include the library.
#include "profiler.h"

int main() {

    // Init the internal Profiler structure. Malloc() gets called, so you need to call clear_profilers() to avoid memory leakage.
    // The log_level filters the log messages that get printed to the console.
    profiler_init(PROFILER_LOG_EVERYTHING);

    // Start the clock of a profiler. The first arguments is used to reference this profiler.
    // The second one is an optional threshold. If the timer exceeds the threshold, the log_level is of type PROFILER_LOG_ALERT instead of PROFILER_LOG_INFO.
    // If the threshold is 0, it gets ignored.
    profiler_begin("Adder", 0);

    // Sample code, that is getting measured.
    long result = 0;
    for (size_t i = 0; i < 1000*1000*1000; ++i) {
        result += i;
    }

    // End the last created profiler. The internal structure is stackbased, so that no comparisons have to be made for more optimal performance.
    profiler_end();

    // Call this function if all the profiling is finished to free the memory allocated by init_profilers().
    profiler_clear();

    return 0;
}
