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now been superceded with an updated version that supports not only block oriented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.
本書第一部分講述的是傳統(tǒng)的網(wǎng)絡(luò)接口N e t B I O S、重定向器以及通過重定向器進(jìn)行的各類
網(wǎng)絡(luò)通信。盡管本書大部分內(nèi)容均圍繞Wi n s o c k編程這一主題展開，但是， A P I比起Wi n s o c k
來，仍然具有某些獨(dú)到之處
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(wǎng)絡(luò)協(xié)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(wǎng)絡(luò)編程接口，而不是協(xié)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(wǎng)絡(luò)協(xié)議。在Wi n 3 2環(huán)境中，Wi n s o c k接口最終成為一個真正的
“與協(xié)議無關(guān)”接口，尤其是在Winsock 2發(fā)布之后。
