NI-IMAQ Libraries
The NI-IMAQ function libraries are dynamic link libraries (DLLs), which means that NI-IMAQ routines are not linked into the executable files of applications. Only the information about the NI-IMAQ routines in the NI-IMAQ import libraries is stored in the executable files.
Import libraries contain information about their DLL-exported functions, indicating the presence and location of the DLL routines. Depending on the development tools you use, you may give the DLL routines information through import libraries or function declarations. Your NI-IMAQ software kit contains function prototypes for all routines.
