Readers can pick up this book and become familiar with C++ in a short time. Stan has taken a very broad and complicated topic and reduced it to the essentials that budding C++ programmers need to know to write real programs. His case study is effective and provides a familiar thread throughout the book.
Structure the sources so that the compression and decompression code
form a library usable by any program, and write both gzip and zip on
top of this library. This would ideally be a reentrant (thread safe)
library, but this would degrade performance. In the meantime, you can
look at the sample program zread.c.
Linux 操作系統(tǒng)是一種性能優(yōu)良、源碼公開(kāi)且被廣泛應(yīng)用的免費(fèi)操作系統(tǒng),由于其體積小、可裁減、運(yùn)行速度高、良好的網(wǎng)絡(luò)性能等優(yōu)點(diǎn),可以作為嵌入式操作系統(tǒng)。隨著2.6內(nèi)核的發(fā)布,Linux向現(xiàn)有主流的RTOS提供商在嵌入式系統(tǒng)市場(chǎng)提出了巨大挑戰(zhàn),例如VxWorks和WinCE,具有許多新特性,將成為更優(yōu)秀的嵌入式操作系統(tǒng)。
