Chapter 9 A Pæan to strtok

This concerns the function ok_array_new(). When strtok_r() fails, we do not free "out" memory.

Last paragraph under ISO C99 subheading in the Preface

"As of this writing, most compilers support C99 plus or minus a few caveats"

In the sentence above, either the word "or" needs to be removed, or perhaps the author intended to write "...support C99 or C11 minus a few caveats".

Last paragraph of the ISO C99 subheading in the Preface

I mistakenly submitted an errata for the last paragraph of the ISO C99 subheading in the Preface.

The text is correct, I had misread it.

Please do not accept my previously reported erratum.

Thanks!

POSIX-standard make has this recipe for compiling a .o object file from a .c source
code file:
$(CC) $(CFLAGS) $(LDFLAGS) -o $@ $*.c

True (gnumake):
$(CC) $(CFLAGS) $(CPPFLAGS) -c -o $@ $<

figure 3-1

In Figure 3-1 the Autotools flowchart depicts 'Automake.am', when the text refers to 'Makefile.am'. The two instances of Automake.am, both in the Authors and Users boxes should be Makefile.am.

Figure 3.1

"You will only be writing two of these files (the shaded ones);"

That should be Makefile.am I think and Automake.am

Took me ages to figure out :-)

example 9-3

Example 9-3 as it appears in the book:

#include <stdio.h>
#include <stdlib.h>

it omits the _GNU_SOURCE before #include <stdio.h> and should be

#define _GNU_SOURCE
#include <stdio.h>
#include <stdlib.h>


By this point in the book the reader should be able to recognize the omission. Perhaps you were simply testing for observation? sasprintf.c from github does not have this omission.

Example 9-3, first comment

On page 187 of 2nd edition, First Release, the first comment in Example 9-3 runs off the page, past the right-hand margin, and part of it seems cut off.
