pango-layout-iter-run-readonly (iter)

iter -- a pango-layout-iter instance

A pango-layout-iter instance with the current run, that should not be modified.

Gets the current run. When iterating by run, at the end of each line, there is a position with a NULL run, so this function can return NULL. The NULL run at the end of each line ensures that all lines have at least one run, even lines consisting of only a newline.

This is a faster alternative to the function pango-layout-iter-run, but the user is not expected to modify the contents of the run (glyphs, glyph widths, etc.).
