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
Address of 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
Address of 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.
