与 stdlib.h中的realloc冲突？
In file included from ex_ftp_basic.h:5,
from 2collector.c:5:
/usr/include/stdlib.h:595: error: conflicting types for 'realloc '
../utils/utils.c:624: error: previous implicit declaration of 'realloc ' was here
/usr/include/stdlib.h:597: error: conflicting types for 'free '
../utils/utils.c:541: error: previous implicit declaration of 'free ' was here

../utils/utils.c：624行如下:
hunk = (char*)realloc (hunk, bufsize);

[解决办法]
hunk = (char*)realloc (hunk, bufsize);这样写是对的，但是用realloc 前必须保证hunk非空，是用malloc分配过的，空间不够继续分配。你再试试！

贴代码，关键部分就可以了！
