In this -tutorial we'll go into a bit more detail. -<P> -ACE_Message_Queue is modeled after Unix System V IPC mechanisms. The basic -idea is that you put a block of data into one end of the Queue and take it -out of the other end. Your basic FIFO in other words. The SysV mechanism -works great for passing these blocks of data between processes on the same -host but it's a bit overkill for moving blocks between threads. You could -use a pipe, socket or similar mechanism but that still has more overhead than -we really want just for moving data between threads. Process-global memory -is a good technique but then you need a way to signal the "listening" threads. -The ACE_Message_Queue is a better approach: Create blocks of data and enqueue -them in one thread while another thread (or threads) dequeue and perform work. -<P> -Kirthika's Abstract: -<UL> -The Message Queue is a FIFO accessible from multiple threads. -That is, a thread puts the produced blocks of data on the message queue -to be consumed by some other thread/threads and processed. In this -tutorial, we see how effectively the Message Queue in a ACE_Task can be -used to pass data among threads in the thread pool. -(this is very similar to -<A HREF="../007/page01.html">Tutorial 7</A> -X wherein we implemented a -thread-pool server).Here, actual data is passed between the threads and -also an ACE_Barrier has been used to provide synchronisation among -multiple threads. -<P> -The Message Queue consists of Message Blocks, each of which has a read -and write pointer. Using these pointers the message blocks can be -accessed for reading and writing operations. The ACE_Task::svc() method -will put the block onto the queue without bothering about the existence -of a consumer for that block. A thread from the thread pool obtains the -block from the queue, and checks to see whether the block_type is -MB_HANGUP. If so, it puts the block back on the queue for its -peers and exits. Otherwise, it reads the block and processes it before -releasing it. -<P> -This simple tutorial makes us aware of the usage and importance of the -Message Queue which could be used to our advantage especially for -multithreaded applications. -</UL> -SHAR_EOF - $shar_touch -am 0124153899 'page01.pre' && - chmod 0664 'page01.pre' || - $echo 'restore of' 'page01.pre' 'failed' - if ( md5sum --help 2>&1 | grep 'sage: md5sum \[' ) >/dev/null 2>&1 \ - && ( md5sum --version 2>&1 | grep -v 'textutils 1.12' ) >/dev/null; then - md5sum -c << SHAR_EOF >/dev/null 2>&1 \ - || $echo 'page01.pre:' 'MD5 check failed' -84d1b63ff2eb7eecec515b248f73d791 page01.pre -SHAR_EOF - else - shar_count="`LC_ALL= LC_CTYPE= LANG= wc -c < 'page01.pre'`" - test 2246 -eq "$shar_count" || - $echo 'page01.pre:' 'original size' '2246,' 'current size' "$shar_count!" - fi -fi -# ============= page02.pre ============== -if test -f 'page02.pre' && test "$first_param" != -c; then - $echo 'x -' SKIPPING 'page02.pre' '(file already exists)' -else - $echo 'x -' extracting 'page02.pre' '(text)' - sed 's/^X//' << 'SHAR_EOF' > 'page02.pre' && -X -We'll look first at <A HREF="message_queue.cpp">main()</A>. -<P> -X -<HR WIDTH="100%"> -SHAR_EOF - $shar_touch -am 0124153399 'page02.pre' && - chmod 0664 'page02.pre' || - $echo 'restore of' 'page02.pre' 'failed' - if ( md5sum --help 2>&1 | grep 'sage: md5sum \[' ) >/dev/null 2>&1 \ - && ( md5sum --version 2>&1 | grep -v 'textutils 1.12' ) >/dev/null; then - md5sum -c << SHAR_EOF >/dev/null 2>&1 \ - || $echo 'page02.pre:' 'MD5 check failed' -166bf09c6c4474767e95ef4a7be20a03 page02.pre -SHAR_EOF - else - shar_count="`LC_ALL= LC_CTYPE= LANG= wc -c < 'page02.pre'`" - test 84 -eq "$shar_count" || - $echo 'page02.pre:' 'original size' '84,' 'current size' "$shar_count!" - fi -fi -# ============= page03.pre ============== -if test -f 'page03.pre' && test "$first_param" != -c; then - $echo 'x -' SKIPPING 'page03.pre' '(file already exists)' -else - $echo 'x -' extracting 'page03.pre' '(text)' - sed 's/^X//' << 'SHAR_EOF' > 'page03.pre' && -Our <A HREF="block.h">Block</A> object is a very simple derivative -of the ACE_Message_Block.
