apue.h头文件(unix环境高级编程)

  apue.h是作者自己写的一个文件,包含了常用的头文件,系统不自带。其中包含了常用的头文件,以及出错处理函数的定义。使用起来确实很方便。

  apue.h内容如下:

  想要使用,还要进行下面操作,完成相关配置.

  在http://www.apuebook.com/下载src.tar.gz源代码的压缩包。

   1、解压至/home/user/目录下

   2、修改 Make.defines.linux中的WKDIR=/home/xxx/apue.2e,为WKDIR=/home/user/apue.2e

   3、返回至apue.2e目录下面,修改linux.mk,将里面的nawk全部改为awk,可以使用这个命令 :%s/nawk/awk/g 

   4、make

   5、将/home/user/apue.2e/include/apue.h和/home/user/apue.2e/lib/error.c复制到/usr/include目录下


    然后就可以方便的使用apue.h编译《unix高级环境编程》的的程序了
