apue.h是做者本身寫的一個文件,包含了經常使用的頭文件,系統不自帶。其中包含了經常使用的頭文件,以及出錯處理函數的定義。使用起來確實很方便。linux
apue.h內容以下: ios

想要使用,還要進行下面操做,完成相關配置.編程
在http://www.apuebook.com/下載src.tar.gz源代碼的壓縮包。函數
一、解壓至/home/user/目錄下ui
二、修改 Make.defines.linux中的WKDIR=/home/xxx/apue.2e,爲WKDIR=/home/user/apue.2ethis
三、返回至apue.2e目錄下面,修改linux.mk,將裏面的nawk所有改成awk,能夠使用這個命令 :%s/nawk/awk/g spa
四、makeunix
五、將/home/user/apue.2e/include/apue.h和/home/user/apue.2e/lib/error.c複製到/usr/include目錄下ip
而後就能夠方便的使用apue.h編譯《unix高級環境編程》的的程序了ci
