// USMCDLL.h - header file with declorations of USMCDLL.dll functions and used structures
// -SD
// Note::C++
// Use functions with reference arguments as in sample
// Note.C
// Use functions with address of operator in invoke expression: func(var1, &struct);
// (For Rev. 24) Will work correctly with firmware version 24.03 or better
