ex-minimal
These examples demonstrate the usage of timemory markers and timemory library for timing measurements. Finally, the ex-minimal-library_overload example demonstrates overloading timemory library record functions with user defined record functions for measurements. The first example is available in C, C++ and Python whereas the last two examples are available in C and C++.
Build
See examples. These examples build the following corresponding binaries: ex_c_minimal, ex_cxx_minimal, ex_c_minimal_library, ex_cxx_minimal_library, ex_cxx_minimal_library_overload, ex_c_minimal_library_overload, ex_python_minimal.
Expected Output
$ ./ex_cxx_minimal
