line 13

On line 13, the 29 graphic characters are displayed. They each have a space in between, except for the pair parentheses. So it would be nice to replace () by ( )
in other words, to put a space between the parentheses, for consistency with the way that the other characters on the line are displayed, with a space in between.

displayed code in the section on wide characters

The line:
wchar_t wc = '\x3b1';
seems to be missing an L
It should read:
wchar_t wc = L'\x3b1';

For comparison, the corresponding line page 11 is correct, but on page 10, the L is missing.

Change "delcared" with "declared"

Example 6.3

The variable `command` should be declared outside of the block in order to be avaiable to the loop controlling condition.

Original Example:
```
do {
int command = ...
} while (command != END);
```

Suggested Example:
```
int command;
do {
command = ...
} while (command != END);
```

Example 7-3

Example 7-3 uses the long double type "in order to accommodate very large results" of the factorial function. According to the book (page 31), the long double format corresponds to the 80 bits extended precision, whose fractional part uses 64 bits. That means that the long double format can represent all integers only up to 2^64. After that, more and more integers are not representable. As a consequence, some results will be rounded (e.g., starting from n=26, factorial(n) as returned by the program in Example 7-3 is wrong).

Using the C99 standard mandated uint_least64_t format, all factorials up to 20 can be computed. The extra range offered by the long double format (correct results up to 25 only) is certainly not worth the trouble and should be strongly discouraged here.

Code snippet at bottom.

The length of the string L"chop suey" is 9, not 10.
Consequently, the array length is 10, and the array size is 10 * sizeof(wchar_t).

Errata in the errata. The issue reported with bufGet not unlocking a mutex says it's on page 367. The listing (Example 14-4) is actually on page 254.

Also, bufPut should unlock the mutex before returning false as well.

"mtx_plain" in "mtx_plain|mtx_recursive" (0|1) has no effect and should be replaced with "mtx_recursive" only

Pretty sure "thread.h" should be "threads.h"

3rd line from top

$(LDFLAGS) should be put at the end of the command, so that the command reads like this:

$(CC) -o $@ $^ $(LDFLAGS)

Similarly the last line on the same page should be updated like this:

gcc -o circle circle.o circulararea.o -lm

This is necessary for the linker to use the libm.a library; otherwise you will get linker errors like "undefined reference to ..." for functions used from this library.
