Primary purpose, in centos6.3 64-bit machines, use Eclipse to learn Apue third edition, And this study does not use the book apue.h, and some libraries under the LIB, or, is the last time the study, encountered the library is directly used, this time I put forward, an adaptation, careful of a function of learning, and use g++ compiler
