[Libexif-devel] Strange C syntax

[Hans U. N. <gp...@n-...>]

I removed the functions containing this code because
 a) some C compilers do not understand it
 b) it is code duplication

But I'd still like to know where this kind of syntax is defined?
Originally C++ and now C99?

I've never seen something like this before:

	return
		exif_tag_get_name_in_ifd (tag, EXIF_IFD_0) ? :
		exif_tag_get_name_in_ifd (tag, EXIF_IFD_1) ? :
		exif_tag_get_name_in_ifd (tag, EXIF_IFD_EXIF) ? :
		exif_tag_get_name_in_ifd (tag, EXIF_IFD_INTEROPERABILITY) ? :
		exif_tag_get_name_in_ifd (tag, EXIF_IFD_GPS);
