Porting the LabVIEW Embedded Run-Time and Analysis Libraries Source Code (Embedded Development Module)
Each LabVIEW function that does not map directly to a C primitive is implemented using a function call. These functions are implemented in the LabVIEW Embedded Run-Time Library on top of a lower layer of generic functions that handle memory movement, string manipulation, timing, and so on.
One of the major components to porting the run-time library is the mapping of these generic, low-level function calls to functions that are supported by your target run-time environment. You must provide this mapping so your toolchain can compile the generated C code for your target platform.
The source code for the LabVIEW Embedded Run-Time Library is located in the following directory:
