This book describes the LabVIEW Manager functions that you can call from external C/C++ code to interact with the underlying infrastructure of LabVIEW. You can use these functions to perform simple and complex operations, ranging from low-level byte manipulation to sorting data and managing memory.

Complete the following steps to use these functions.

  1. Include the header file extcode.h and link to labviewv.lib in any C/C++ files from which you want to call the functions.
  2. Use the function signatures in this book to call the functions.
  3. Create a shared library of these source files.
  4. Use the Call Library Function Node to call the shared library in LabVIEW.
