HP aC++/HP C A.06.20 Release Notes

return 0;

Notes:
• The quantize functions do the work of rounding to the desired number of places
to the right of the decimal point. They return the value of their first argument
represented with the quantum exponent of their second argument, rounding if
necessary.
• Mixing decimal FP and integer operands, as in the expression m / 60, is allowed.
However, the expression m / 60.0, which mixes decimal and binary FP, would
cause an error.
• On the HP-UX implementation, BID data could be read directly into the decimal
FP variable m, without the need of decoding. However, that code would not be
portable to systems that use DPD encoding for their decimal FP types.
• Restoring the default rounding has no effect in this program, except perhaps if the
ASCII input had more than 16 decimal digits, but doing so is a good programming
practice.
+annotate=structs (New)
The +annotate=structs option annotates the compiled binary with accesses to
C/C++ struct fields for use by other external tools such as Caliper. By default, no
annotations are added.
+check=lock (New)
The new runtime +check=lock option enables the checking of locking discipline
violations; for example, whether appropriate locks are held when threads access shared
data in applications using Posix threads. Refer to the online programmer's guide for
additional detail and code example. Note that +check=lock is not enabled by
+check=all.
+check=thread (New)
The new runtime +check=thread option enables the batch-mode thread-debugging
features of HP WDB. This feature requires HP WDB 5.9 or later. The following
thread-related conditions can be detected with +check=thread:
• The thread attempts to acquire a nonrecursive mutex that it currently holds.
• The thread attempts to unlock a mutex or a read-write lock that it has not acquired.
• The thread waits (blocked) on a mutex or read-write lock that is held by a thread
with a different scheduling policy.
• Different threads non-concurrently wait on the same condition variable, but with
different associated mutexes.
• The threads terminate execution without unlocking the associated mutexes or
read-write locks.
