csh question

[Eric Marshall]

	Why can't csh use stdio? Looking at the csh code, csh has its
own printf routine which prints using putchar, instead of putc, which
is what stdio uses. What's the difference between the two? The infamous
doprnt routine is also different. The makefile for csh contains
a comment that an old doprnt needs to be used whose output we
can trap. What does that mean? Whats this all about?

Thanks in advance.
