1 In LabWindows™/CVI™, C, and C++, constant names such as NIDMM_VAL_TRUE and
NIDMM_VAL_AUTO_ZERO_ON refer to the use of #defines in your program. In LabVIEW, these constants
refer to Boolean or ring controls with corresponding entries. For example, NIDMM_VAL_AUTO_ZERO_ON
corresponds to the LabVIEW ring control entry Auto Zero On. Refer to LabVIEW Help (Show Help) for
more details.
