);

Parameters

Plug-and-Play capture drivers are enumerated first, followed by capture drivers listed in the registry, which are then followed by capture drivers listed in SYSTEM.INI.

lpszName

Pointer to a buffer containing a null-terminated string corresponding to the capture driver name.

cbName

Length, in bytes, of the buffer pointed to by lpszName.

lpszVer
