maildir_canon_filename()

void maildir_canon_filename	(	struct Buffer *	dest,
		const char *	src
	)

Generate the canonical filename for a Maildir folder.

Parameters

dest	Buffer for the result
src	Buffer containing source filename

Note

maildir filename is defined as: <base filename>:2,<flags> but <base filename> may contain additional comma separated fields. Additionally, : may be replaced as the field delimiter by a user defined alternative.
