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.
