6. Building an Application with SX12 DLL
The following files are distributed with sx12.dll:
sx12.h
– contains data types and constants definitions;
sx12f.h – contains exported functions declarations;
sx12app.c – contains exported functions and helper functions definitions.
When building an application with sx12.dll, it is necessary to include sx12app.c in the project.
If MFC is used, an option "Not using precompiled headers" must be set in the project settings for
sx12app.c.
All modules containing calls to the sx11.dll functions must include sx11f.h. Please refer to the
sample source code for an example of building an application with SX12 DLL.
7. Functions Reference
The SX12 DLL is designed to provide the application developer with full control over the frame grabber.
All special data types used by the DLL are defined in sx12.h. The sample application illustrates the use of
most of the functions and allows building a custom application within minutes.
