A QDir can point to a file using either a relative or an absolute path. Absolute paths begin with the directory separator "/" (optionally preceded by a drive specification under Windows). If you always use "/" as a directory separator, Qt will translate your paths to conform to the underlying operating system. Relative file names begin with a directory name or a file name and specify a path relative to the current directory. The "current" path refers to the application's working directory. A QDir's own path is set and retrieved with setPath() and path(). An example of an absolute path is the string "/tmp/quartz", a relative path might look like "src/fatlib". You can use the function isRelative() to check if a QDir is using a relative or an absolute file path.

The file name is usually passed in the constructor but can be changed with setName().

If the library is a component server, QLibrary provides access to the exported component and can directly query this component for interfaces. QLibrary ensures that the shared library is loaded and stays in memory whilst it is in use. QLibrary can also unload the library on destruction and release unused resources. A typical use of QLibrary is to resolve an exported symbol in a shared object, and to call the function that this symbol represents. This is called "explicit linking" in contrast to "implicit linking", which is done by the link step in the build process when linking an executable against a library. The following code snippet loads a library, resolves the symbol "mysymbol", and calls the function if everything succeeded. If something went wrong, e.g. the library file does not exist or the symbol is not defined, the function pointer will be 0 and won't be called. When the QLibrary object is destroyed the library will be unloaded, making all references to memory allocated in the library invalid. @@ -305,39 +305,40 @@ void QLibrary::setAutoUnload( bool enabled ) Returns the filename of the shared library this QLibrary object handles, including the platform specific file extension.

Unfortunately the regexp is rather long and not very versatile -- the code will break if we add any more fields.

Notice that we can't match both \c .html and \c .htm files with a wildcard unless we use <b>*.htm*</b> which will also match 'test.html.bak'. A full regexp gives us the precision we need, <b>.*\\.html?$</b>. QRegExp can match case insensitively using setCaseSensitive(), and can use non-greedy matching, see setMinimal(). By default QRegExp uses full regexps but this can be changed with setWildcard(). Searching can be forward with search() or backward with searchRev(). Captured text can be accessed using capturedTexts() which returns a string list of all captured strings, or using cap() which returns the captured string for the given index.

The \a mutex must be initially locked by the calling thread. If \a mutex is not in a locked state, this function returns immediately. If \a mutex is a recursive mutex, this function returns immediately. The \a mutex will be unlocked, and the calling thread will block until either of these conditions is met: \list \i Another thread signals it using wakeOne() or wakeAll(). This function will return TRUE in this case. \i \a time milliseconds has elapsed. If \a time is ULONG_MAX (the default), then the wait will never timeout (the event must be signalled). This function will return FALSE if the wait timed out. \endlist The mutex will be returned to the same locked state. This function is provided to allow the atomic transition from the locked state to the wait state. \sa wakeOne(), wakeAll() */ bool QWaitCondition::wait(QMutex *mutex, unsigned long time) { if (! mutex) return FALSE; if (mutex->d->type() == Q_MUTEX_RECURSIVE) { #ifdef QT_CHECK_RANGE qWarning("Wait condition warning: using recursive mutexes with\n" " wait conditions is undefined!"); #endif return FALSE; } int ret; if (time != ULONG_MAX) { struct timeval tv; gettimeofday(&tv, 0); timespec ti; - ti.tv_nsec = (tv.tv_usec * 1000) + (time % 1000) * 1000; + ti.tv_nsec = ( tv.tv_usec + ( time % 1000 ) * 1000 ) * 1000; ti.tv_sec = tv.tv_sec + (time / 1000) + ( ti.tv_nsec / 1000000000 ); ti.tv_nsec %= 1000000000; ret = pthread_cond_timedwait(&d->cond, &mutex->d->handle, &ti); } else ret = pthread_cond_wait(&d->cond, &mutex->d->handle); #ifdef QT_CHECK_RANGE if (ret && ret != ETIMEDOUT) qWarning("Wait condition wait failure: %s",strerror(ret)); #endif return (ret == 0); } #endif // QT_THREAD_SUPPORT |
