Module Name:
hidphone.c
Abstract:
This module contains implements the phone tsp functions is called by
tapi in order to access the HID compliant USB phone device.
This module communicates with the phone device using the HID interface.

Locking Mechanism:
There are two critical section objects being used inorder to protect
the phone structure from simultaneous access - csAllPhones and
csThisPhone. Every phone has one csThisPhone, the critical section
object, associated with it. csThisPhone ensures that the Phone Info
is accessed in a thread-safe manner. csAllPhones is a global Critical
Section Object that ensures that a thread acquires the csThisPhone
Critical Section Object in a thread safe manner. In other words, it
ensures that, the thread waits on csThisPhone while the Critical
Section Object is still valid.
The csAllPhones should always be acquired before csThisPhone.
A phone can be closed only after the thread has acquired both
csAllPhones and csThisPhone for the specific phone to be closed. Both
these objects are released only after the function is completed. For
all other functions, the csAllPhones critical section is released as
soon as the thread acquires csThisPhone object.

TSPI_providerInit:
The TSPI_providerInit function initializes the service provider and gives
it parameters required for subsequent operation.
Arguments:
dwTSPIVersion - The version of the TSPI definition under which
this function must operate.
dwPermanentProviderID - The permanent identifier, unique within the TSP
on this system, of the TSP being initialized.
dwLineDeviceIDBase - Ignored by this TSP
dwPhoneDeviceIDBase - The lowest device identifier for the phone
devices supported by this service provider.
dwNumLines(Ignored) - The number of line devices this TSP supports.
dwNumPhones - The number of phone devices this TSP supports.
The value returned is the number of phone
devices reported in TSPI_providerEnumDevices.
lpfnCompletionProc - The procedure the TSP calls to report
completion of all asynchronously operating
procedures on line and phone devices.
lpdwTSPIOptions - A pointer to a DWORD-sized memory location,into
which the TSP can write a value specifying
LINETSPIOPTIONS_ values. This parameter allows
the TSP to return bits indicating optional
behaviors desired of TAPI. TAPI sets the
options DWORD to 0.
Returns LONG:
Zero if the request succeeds or
An error number if an error occurs.
