This application note describes a method for developing block-oriented I/O device drivers
for applications that use the DSP/BIOS real-time kernel and includes examples that run
with Code Composer Studio v2.1 on the Texas Instruments TMS320C5402 and
TMS320C6711 DSP Starter Kits (DSKs). The device driver model presented here has
now been superceded with an updated version that supports not only block oriented
devices, but also devices such as UARTs, PCI and USB buses and Multimedia cards.
Documentation on the updated driver model as well as example drivers and source code
can be found in the Device Driver Developer s Kit product now available for download
from the TI Developer s Village.
本書第二部分講述的是在Wi n 3 2平臺上的Wi n s o c k編程。對于眾多的基層網絡協議，
Wi n s o c k是訪問它們的首選接口。而且在每個Wi n 3 2平臺上，Wi n s o c k都以不同的形式存在著。
Wi n s o c k是網絡編程接口，而不是協議。它從U n i x平臺的B e r k e l e y（B S D）套接字方案借鑒了
許多東西，后者能訪問多種網絡協議。在Wi n 3 2環境中，Wi n s o c k接口最終成為一個真正的
“與協議無關”接口，尤其是在Winsock 2發布之后。
