C编程 头文件 求助

dustmoon

怎么样 把自己定义的一个头文件  apue.h 弄成和stdio.h 那样  可以全局调用呢？

  就是没把apue.h 放在一个文件  也可以Include它

[PHP]
-I dir
       Add the directory dir to the list of directories to be searched for
       header files.  Directories named by -I are searched before the
       standard system include directories.  If the directory dir is a
       standard system include directory, the option is ignored to ensure
       that the default search order for system directories and the spe-
       cial treatment of system headers are not defeated .

放在系统的include 目录中，或在makefile 中用 I  添加进去
