= Basically, I apologize for the "flame" that people seem to think I
= posted. I wasn't flaming really. I just meant to point out that
= puts() will never be slower than printf(), so to avoid "other bugs"
= (see below), it's safer to use puts when that's what you really meant.
= Sorry, Michael.
No offense taken.
As to "puts() will never be slower than printf()": I recall reading

= No, I was talking about the type of bug that lint can't catch. That is,
= I see this type of usage all the time:
=
= ...
= send_to_file("this is a string");
= ...
=
= send_to_file(s)
= char *s;
= {
= extern FILE *fp;
= fprintf(fp, s);
= }
You must look at some strange progams :-)
I aggree that this is bad practice and people should be made aware of
it.
