Corrections

p. 9
The code example declares my_chunk to be of type GMemChunk. It should instead be declared as a pointer, so instead of:

GMemChunk my_chunk
it should be:

GMemChunk *my_chunk

p. 11
The last two examples in the code snippet:

/* the same thing, with g_mem_chunk_new */ foo = g_mem_chunk_new(footype, pile_of_mem);

/* the same thing, but zero out the memory */ foo = g_mem_chunk_new0(footype, pile_of_mem);

The calls (and the first comment) should be to the macros g_chunk_new and g_chunk_new0 rather than to g_mem_chunk_new and g_mem_chunk_new0.

The paragraph following the example beginning "The macros' purposes..." should also reference g_chunk_new and g_chunk_new0 as the memory chunk counterparts of g_new and g_new0 rather than the g_mem_chunk functions.

p. 12
The last code example ("Here is a short quark demonstration program:")

my_quark should be defined as a GQuark, not a pointer to a GQuark.

The line:

if (!g_quark_try("Cottage Cheese"))

should be:

if (!g_quark_try_string("Cottage Cheese"))

p. 36
The second function call to g_string_free() should be:

orig_str = g_string_free(s2, FALSE); /* s2 is gone; orig_str points to its old str field */

p. 256
The function: gint gnome_score_log(gfloat score, const gchar *score, gboolean descending)

should be:

gint gnome_score_log(gfloat score, const gchar *level, gboolean descending)

p. 290
In Chapter 4 of the Gnome 2 examples, there's a syntax error in one of the files. On line 186 of druid.c, it reads:

the bar at the top remains.\n\n

but it should be:

the bar at the top remains.\n\n\

p. 336
In the miracletext.desktop example file:
The second line (Name=Example) should be removed
The Name and Comment entries should be swapped
The file names should refer to miracletext, not "example"

The corrected file should look like this:

[Desktop Entry]
Name=MiracleText Word Processor
Name[de]=MiracleText Textverarbeitung
Name[es]=MiracleText procesador de textos
Comment=Edit documents with MiracleText
Comment[de]=Dokumente bearbeiten mit MiracleText
Comment[es]=Edita documentos con MiracleText
TryExec=miracletext
Exec=miracletext %U
Icon=miracletext.png
Terminal=0
Type=Application
Categories=Application

Note: A reader commented that on page 81, media_set_orig_package implies that media_set_property calls g_object_notify, but the call is not present in the code on page 79.
