Author:
Dan Knudson (DanKn) 11-Apr-1995
Revision History:
Notes:
1. NdisTapi.sys needs to be modified to support IOCTL_DISCONNECT so we
don't have to close all the driver handles etc each time we get a
providerShutdown request (ideally we ought only have to close handles,
etc on a dll process detach).
2. There's the hack in TSPI_providerInit where tapisrv has to pass in
pointer to dwNumLines & dwNumPhones, becuase we determine the # of
devs when we send the CONNECT IOCTL
3. Ndistapi.h is not in sync w/ tapi.h & tspi.h, so make sure to use
the definitions in ndistapi.h as appropriate (like LINE_DEV_CAPS
instead of LINEDEVCAPS).
4. A slight perf gain might be realized by caching dev caps info for
each line (but can/will it chg on the fly?)
5. To keep bad 2.0 apps from blowing up if they try to look at version
1.4 or 2.0 structure fields we pad the area between the end of the
1.0 structure and the variable-length data with 0's. This is done
in GetAddrCaps, GetCallInfo, GetCallStatus, GetDevCaps, &
GetLineDevStatus.
6. Since TAPI 2.0 service providers are required to be 100% unicode,
kmddsp munge all incoming unicode strings to ascii before passing
them to an underlying driver, and also converts all returned ascii
strings (embedded in structures) to unicode.
