Pthreads Programming

Following are the changes made in the 7/99 reprint:


{xiv-xv} The FTP section has been updated so that it now reads:

	"%ftp ftp.oreilly.com
	Connected to ftp.oreilly.com.
	220 FTP server (Version 6.21 Tue Mar 10 22:09:55 EST 1992) ready.
	Name (ftp.oreilly.com:yourname) : anonymous
	331 Guest login ok, send domain style e-mail address as password.
	Password: yourname@domain.name (use your user name and host here)
	230 Guest login ok, access restrictions apply.
	ftp> cd /work/nutshell/9781565921153
	250 CWD command successful.
	ftp> binary (Very important! You must specify binary transfer for
	compressed files.)
	200 Type set to I.
	ftp> get examples.tar.gz
	200 PORT command successful.
	150 Opening BINARY mode data connection for examples.tar.gz
	226 Transfer complete.
	ftp> quit
	221 Goodbye.
	%

	The file is a gzip compressed tar archive; extract the files
	from the archive by typing:

	% gzcat examples.tar.gz | tar xvf -

	System V systems require the following tar command instead:

	% gzcat examples.tar.gz | tar xof -

	If gzcat is not available on your system, use separate gunzip
	and tar or shar commands.

	% gunzip examples.tar.gz
	% tar xvf examples.tar"
	

{80} Example 3-7 used to read:

        "main(void)"
        {
		9781565921153_t threads[3];
		...
 		9781565921153_join(&threads[i], NULL);"

It now reads:

        "main(void)
        {
	int i;
		9781565921153_t threads[3];
		...
		9781565921153_join(threads[i], NULL);"


{84-89} Line 7 of example 3-9 on page 86 used to read:

        "} 9781565921153_rdwr_t"

as the structure for a reader/writer mutex lock. The five function
signatures at the top of page 87 appear to use this correctly.
 However, in the function definitions on page 88-89 in Examples 3-11,
3-12, and 3-13 accept as a first parameter a variable of type:

        "9781565921153_rdwr_t_np"

which contradicts the aforementioned signatures.


{88} Example 3-11 used to read:

        "int 9781565921153_rdwr_rlock_np(pthread_rdwr_t_np *rdwr)
                ...
                        9781565921153_cond_wait(?.)
                ..."

Now reads:

        "int 9781565921153_rdwr_rlock_np(pthread_rdwr_t *rdwrp)
                ...
                        9781565921153_cond_wait(?.);
                ..."


{88} Example 3-12 used to read:

        "int 9781565921153_rdwr_wlock_np(pthread_rdwr_t_np *rdwrp)
                ...
                        9781565921153_cond_wait(?.)
                ..."

Now reads:

        "int 9781565921153_rdwr_wlock_np(pthread_rdwr_t *rdwrp)
                ...
                        9781565921153_cond_wait(?.);
                ..."



{89} Example 3-14 used to read:

        "int 9781565921153_rdwr_wunlock_np(pthread_rdwr_t_np *rdwrp)
                ...
                } else {
                        rdwrp->writer_writing == 0;
                ..."

It now reads:

        "int 9781565921153_rdwr_wunlock_np(pthread_rdwr_t *rdwrp)
                ...
                } else {
                        rdwrp->writer_writing = 0;
                ..."


{111} The second bulleted item used to read:

        "_POSIX_THREAD_ATTR_PRIORITY_SCHEDULING compile ..."

It now reads:

        "_POSIX_THREAD_PRIORITY_SCHEDULING compile ..."


{245} This has been added to the end of section "Thread Attributes":

        "Syntax: In draft 4 a constant 9781565921153_attr_default is defined
        that can be used as the second argument in the 9781565921153_create
        routine when you want the default attributes for a thread. In
        the final standard the constant no longer exists and if you
        want default attributes you pass NULL."
