Do proper error checking and return -1 on fail.

2002-09-10  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-folder-summary.c (perform_content_info_save): Do proper
	error checking and return -1 on fail.
	(camel_folder_summary_save): Check the return of
	perform_content_info_save and a few other output calls within the
	message_info_save loop. If any of them fail, save errno, close the
	file, and return -1. If we finish the loop without fail, fflush
	the stream and then fsync (fflush only flushes user-space buffers,
	you still need to fsync afterward to flush the data to disk). If
	either fail, treat it as an exception by saving errno, closing the
	stream, and returning -1. I suspect that this also fixes bug
	#30150 because the old code would fclose if fflush or fclose
	failed in the check after the loop (man fclose(3) states that any
	further calls using the stream (even another call to fclose) will
	have undefined behaviour no matter what the first fclose call
	returned).

	* providers/local/camel-local-summary.c
	(camel_local_summary_init): Don't malloc a private struct of 0
	size.
