-> dosFsMkfs(/fd0，pdev)
-> fd=creat(/fd0/myfile,2) or -> fp=fopen(/fd0/myfile,w)
-> buf=what you want to write to file
-> write(fd,buf,strlen(buf)+1) or -> fprintf(fp,buf)
-> close(fd) or -> fclose(fp)
2.open file and read contents from floopy disk:
-> readbuf=malloc(100)
-> fd=open(/fd0/myfile,2) or -> fp=fopen(/fd0/myfile,r)
-> read(fd,readbuf,100) or -> fread(readbuf,1,50,fp)
-> printf readbuf
-> close(fd) or -> close(fp)
3.on simpc shell:
-> fp=fopen(host:d:/temp/myfile,w)
-> fprintf(fp,kjkkhjk)
-> fclose(fp)
