To use your Matrox Vio Analog or Matrox Vio Duo with MIL, you must allocate a MIL Vio system (M_SYSTEM_VIO), with MsysAlloc(). This allocation opens communication with the Matrox Vio and allows MIL to use its resources. You can run only one process (executable) on your Matrox Vio. The process can allocate a system for Matrox Vio only once.
Refer to the Matrox Vio release notes for any additions/modifications to this chapter or in the MIL Reference.
