capGetDriverDescription

The capGetDriverDescription function retrieves the version description of the capture driver.

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

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

Return Values

Returns TRUE if successful or FALSE otherwise.

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.

Requirements

  Windows NT/2000/XP: Included in Windows NT 3.1 and later.
  Windows 95/98/Me: Included in Windows 95 and later.
  Header: Declared in Vfw.h.
