对二进制数据文件格式进行重新排序的C程序源码。例如有很多个站的很多时刻的观测数据。本程序将以时间排序的数据变为以站点排序的数据，适应很多工程处理的需要。-Reordering of the binary data file format C program source. For example, the observational data of many stations a lot of time. This procedure will be time to sort the data

实现文件的读取，从第n行开始读取下一行数据-Implementation file to read from the first line n reads the next line of data
