Routine Description:
Returns information about various handle-specific variables
Arguments:
hInternet - handle of object for which information will be
returned
dwOption - the handle-specific INTERNET_OPTION to query
lpBuffer - pointer to a buffer which will receive results
lpdwBufferLength - IN: number of bytes available in lpBuffer
OUT: number of bytes returned in lpBuffer
Return Value:
BOOL
Success - TRUE
Failure - FALSE. Call GetLastError() for more info:
ERROR_INVALID_HANDLE
hInternet does not identify a valid Internet handle
object
ERROR_INTERNET_INTERNAL_ERROR
Shouldn't see this?
ERROR_INVALID_PARAMETER
One of the parameters was bad
ERROR_INSUFFICIENT_BUFFER
lpBuffer is not large enough to hold the requested
information; *lpdwBufferLength contains the number of
bytes needed
ERROR_INTERNET_INCORRECT_HANDLE_TYPE
The handle is the wrong type for the requested option
ERROR_INTERNET_INVALID_OPTION
The option is unrecognized
