Redirecting printf() does not work
Hi,
Regarding the ‘#’ characters, its because a sharp as first character of a line is introducing a numbered list item (like a star will introduce an unnumbered, dot, lost); two sharps (or two stars) introduce sublist items and so on...
To avoid that just include your code between {CODE()} and {CODE}, as I’ve done in your message above. (by the way to display special characters or syntax, surround them between ~np~ and ~/np~). You have a quite exhaustive presentation of the Wiki syntax used on this site (which is based on tiki-wiki) at https://doc.tiki.org/Wiki-Syntax+Text
To come back to your original problem, what you have done should work; are you sure the file in which you define the PUTCHAR_PROTOTYPE function was effectively included in your executable? If it is in a file that is only needed for this function, it may be omitted; try putting this function in your main program for example.
