Changes between 0.9.8b and 0.9.9 [xx XXX xxxx]
+ *) In addition to the numerical (unsigned long) thread ID, provide
+ for a pointer (void *) thread ID. This helps accomodate systems
+ that do not provide an unsigned long thread ID. OpenSSL assumes
+ it is in the same thread iff both the numerical and the pointer
+ thread ID agree; so applications are just required to define one
+ of them appropriately (e.g., by using a pointer to a per-thread
+ memory object malloc()ed by the application for the pointer-type
+ thread ID). Exactly analoguous to the existing functions
+
+ void CRYPTO_set_id_callback(unsigned long (*func)(void));
+ unsigned long (*CRYPTO_get_id_callback(void))(void);
+ unsigned long CRYPTO_thread_id(void);
+
+ we now have additional functions
+
+ void CRYPTO_set_idptr_callback(void *(*func)(void));
+ void *(*CRYPTO_get_idptr_callback(void))(void);
+ void *CRYPTO_thread_idptr(void);
+
+ also in <openssl/crypto.h>. The default value for
+ CRYPTO_thread_idptr() if the application has not provided its own
+ callback is &errno.
+ [Bodo Moeller]
+
*) Change the array representation of binary polynomials: the list
of degrees of non-zero coefficients is now terminated with -1.
Previously it was terminated with 0, which was also part of the
file.
Multi-threaded applications must provide two callback functions to
-OpenSSL. This is described in the threads(3) manpage.
-
+OpenSSL by calling CRYPTO_set_locking_callback() and
+CRYPTO_set_id_callback(). (For OpenSSL 0.9.9 or later, the new
+function CRYPTO_set_idptr_callback() may be used in place of
+CRYPTO_set_id_callback().) This is described in the threads(3)
+manpage.

B<file> and B<line> are the file number of the function setting the
lock. They can be useful for debugging.
-id_function(void) is a function that returns a thread ID, for example
-pthread_self() if it returns an integer (see NOTES below). It isn't
-needed on Windows nor on platforms where getpid() returns a different
-ID for each thread (see NOTES below).
+id_function(void) is a function that returns a numerical thread ID,
+for example pthread_self() if it returns an integer (see NOTES below).
+By OpenSSL's defaults, this is not needed on Windows nor on platforms
+where getpid() returns a different ID for each thread (see NOTES
+below).
+
+idptr_function(void) is a function that similarly returns a thread ID,
+but of type void *. This is not needed on platforms where &errno is
+different for each thread. OpenSSL assumes that it is in the same
+thread iff both the numerical and the pointer thread ID agree, so it
+suffices to define one of these two callback functions appropriately.
Additionally, OpenSSL supports dynamic locks, and sometimes, some parts
of OpenSSL need it for better performance. To enable this, the following
all threads.
There is still the issue of platforms where pthread_self() returns
-something other than an integer. This is a bit unusual, and this
-manual has no cookbook solution for that case.
+something other than an integer. It is for cases like this that
+CRYPTO_set_idptr_callback() comes in handy. (E.g., call malloc(1)
+once in each thread, and have idptr_function() return a pointer to
+this object.)
=head1 EXAMPLES
CRYPTO_num_locks() was added in OpenSSL 0.9.4.
All functions dealing with dynamic locks were added in OpenSSL 0.9.5b-dev.
+CRYPTO_set_idptr_callback() was added in OpenSSL 0.9.9.
