capGetDriverDescription function
The capGetDriverDescription function retrieves the version description of the capture driver.
Syntax
BOOL VFWAPI capGetDriverDescription( WORD wDriverIndex, LPTSTR lpszName, INT cbName, LPTSTR lpszVer, INT cbVer );
Parameters
- wDriverIndex
-
Index of the capture driver. The index can range from 0 through 9.
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
-
Pointer to a buffer containing a null-terminated string corresponding to the description of the capture driver.
- cbVer

Return value

Remarks
If the information description is longer than its buffer, the description is truncated. The returned string is always null-terminated. If a buffer size is zero, its corresponding description is not copied.
