Macro Definition

• PROF: encapsulates profiling statements. Use the ENABLE\_PROF macro to control whether profiling is enabled during compilation. PROF supports one or two parameters.

  • One parameter: profiling statement.

    If ENABLE\_PROF is defined, the print statement is executed. If it is not defined, printing is skipped.

    PROF(std::cout**<<** "enable prof" << std::endl);

  • Two parameters: profiling level and profiling statement. Automatically initializes the Profiler class and defines the profiling level.

    If ENABLE\_PROF is defined, profiling is executed. If it is not defined, no profiling occurs. The Profiler class is automatically initialized.

    PROF(INFO, Attr("req", 1).Event("recv"));

• ENABLE\_PROF: works with PROF. If this environment variable is not defined, profiling is disabled, and PROF is automatically defined as empty. Generally, it is defined in CMakeLists.txt.
