This flowchart may help. It's taken from my book, Symbian OS Explained (page 76), with some modification:

A descriptor is a data structure that describes a string or an array. Each descriptor contains information that describes the type of the data being referenced, the size of the data, and the address of the data. It also includes a description of the storage used for the data, typically static or dynamic. Descriptors are passed by reference.

Yes you can, but don't. For example you could specify your function requiring a parameter passed a TBuf<10>&. But what if the caller has got a TPtrC, or an HBufC, or even a TBuf<11>? This means that they won't be able to call your function without some extra hassle to fit in with exactly what you have specified. TDes and TDesC are the most general types you can use for your function parameters. Oh how much pain has this one caused? Missing out that little & symbol makes all the difference.

Vinyl acrylic paint (Off Broadway) is used right out of the can which makes it easy to use. It’s especially good if you're working with K-12 students. It will adhere to almost any surface, colors are intermixable and white-white is used to “white out” other colors. Supersaturated Roscopaint is versatile. It can be diluted substantially (1:3-20 parts water) without losing its binder strength which makes it a good choice for watercolor effects, layering and translucent washes.

Could you tell me what the option "-lsocket -lnsl" is used for? How can I find this kind of options with command man? ( I tried man gcc, but cannot find them)

You will have to search the filesystem for files of the same size as the file you're reading, and compare information in them to find the file you're working on.

CPCAB Descriptors are attached to the main qualification titles, and can either refer to the model, e.g. humanistic, psychodynamic etc, or to the context or setting of the work, e.g. Certificate in Counselling Skills - Working with Addictions; Certificate in Counselling Skills - Working With Young People. Depending on what options colleges make available, trainees can choose between a Humanistic, Psychodynamic or Integrative Diploma.

A distance descriptor is a structural feature consisting of two atoms or groups that have a fixed spatial distance from each other. The number and type of atoms and bonds that separate the two end groups of a distance descriptor are indeterminate.

This is also easy. First you must call HBufC::Des() to get a TPtr, which is modifiable. You can then use that:

If you have a very efficient filtration system that can maintain pristine water quality, you can keep more fish.

You must use sufficient Vaseline for lubrication or it will sting. Coat the suppository and add a dollop to the tip as well.

Your horse should be at least six years old and well broken. Be sure your stock are accustomed to crossing bridges, logs, streams, and rocky areas as these are common during backcountry travel. Remember, the PCT is not a speed trail and that most gaited horses like flat roads.

What you use for crankcase oil in your 4 cycle (Gilson) snowblower has become a complicated question. Most engines are permanently marked with a suggested oil for winter use. That recommendation has changed over time and oil technology has also advanced. Many older engines suggested SAE 10W oil for winter use. Along the way it became SAE 5-20. I'm sure there have been other variations as well. Either one of these oils will do a fine job in moderate winter temperatures.

Use white lithium spray lube or engine oil to lubricate pivot points of moving parts within the hitch. The pivoting points inside the hitch head should be lubricated with a white lithium spray lube. You will also want to lubricate the length of the interior handle and the coils of the springs. This will allow for easier operation of hitch. The pivoting points outside should be lubricated with a high pressure lubricant such as a 80/90 gear lube or a grease.

We are equipped with new Celestron Nexstar 9.25" GPS telescopes. They are equipped with Celestron's new Starbright XL coatings for 10% more light throughput than ordinary instruments. These scopes are computer automated and have spectacular optics. Because they are bigger and have better optics they gather about 45% more light than telescopes used on other tours.

There are a lot of products to choose from, and much of the decision depends on individual preference. A fluoride toothpaste is essential for optimal oral health. Beyond that, your dental hygienist and dentist can alert you to any other features that make one product more suitable than another for you as an individual.

Up until March 29, 2004 I was using an old Fuji FinePix 1400 Zoom digital camera (1.3 MP). On March 29, 2004 I began using a Fuji S7000 digital camera (6.6 MP). I love the new camera. Back to index

This is a tough one to answer, because fertilization is so tremendously tied to water quality, potting medium, temperature, light and a variety of other factors. However, if you just have a few plants, and don't want to fuss around a lot learning about the intricacies of water and fertilizer, I'd simply suggest you get any reasonably balanced 'orchid' fertilizer, that is low in urea, and use it at approximately 1/4 to1/2 the label strength every other watering.
