Changchun:
For some strange file, according to API description, we shouldn't check
resolved_path as it is undefined.
To make the loop go on, we could use "continue" when we detect path is NULL.
RETURN VALUE
If there is no error, realpath() returns a pointer to the resolved_path.
Otherwise it returns a NULL pointer, and the contents of the array
resolved_path are undefined, and errno is set to indicate the error.
