Parameters:

p_context
p_parent_dir_handle	Handle of the parent directory
p_fsalname	Name of the object
p_infofs	Information about the file (taken from the filesystem) to be compared to information stored in database
p_children	fsal_posixdb_child array (that contains the entries of the directory stored in the db)

		fsal_name_t *	p_fsalname,
		fsal_posixdb_fileinfo_t *	p_infofs,
		posixfsal_handle_t *	p_object_handle
	)

Get the handle of a file, knowing its name and its parent dir.

Parameters:

p_context
p_parent_dir_handle	Handle of the parent directory
p_fsalname	Name of the object
p_infofs	Information about the file (taken from the filesystem) to be compared to information stored in database

		posixfsal_handle_t *	p_handle,
		int	is_dir,
		fsal_path_t *	p_fsalpath,
