![]() ![]() However, an array variable or symbol name can be used in any context where a pointer is permitted. Arrays may not be assigned as a whole in D. If x and y are scalar array variables, the expression x = y is not legal. If x and y are pointer variables, the expression x = y is legal it simply copies the pointer address in y to the storage location named by x. This difference is manifested in the D syntax if you attempt to assign pointers and scalar arrays. This difference is illustrated in the following diagram: Figure 5–2 Pointer and Array Storage An array variable names the array storage itself, not the location of an integer that in turn contains the location of the array. The difference between pointers and arrays is that a pointer variable refers to a separate piece of storage that contains the integer address of some other storage. As always, you can't damage DTrace itself or your operating system, but you will need to debug your D program. If you access memory beyond the end of an array's predefined value, you will either get an unexpected result or DTrace will report an invalid address error, as shown in the previous example. Array bounds checking is not performed for you by the compiler or DTrace runtime environment. One consequence of this equivalence is that C and D permit you to access any index of any pointer or array. Because p now contains the same address associated with a, this expression yields the same value as a, shown in the right-hand fragment. The expression p traces the value of the third array element (index 2). In the left-hand fragment, the pointer p is assigned to the address of the first array element in a by applying the & operator to the expression a. For example, the following two D fragments are equivalent in meaning: p = &a trace(a) A pointer is also the address of a storage location with a defined type, so D permits the use of the array index notation with both pointer variables and array variables. An array is represented by a variable that is associated with the address of its first storage location. The conversation will be available on the Getty Research Institute YouTube channel following the event.Pointers and arrays have a special relationship in D, just as they do in ANSI-C. This program is part of The Fragment series, which explores how fragments have long catalyzed the study of visual culture while also continuing to inform contemporary views of society and art. Talk title: Breaking the Body and Building the World in Christian Fraction Rites His current research examines how images of Christ's body–"broken up but not divided"–served to allegorize the fractured condition of the Christian world. John Lansdowne, an art historian of the Middle Ages, is a postdoctoral fellow and assistant to the director at Villa I Tatti, the Harvard University Center for Italian Renaissance Studies. Talk title: Harvest/Transformation, Repair/Dissolution: Extended Lives of Andean Trophy Heads and Implications for Past and Modern Collections She explores patterns in skeletal markers of social violence, inter- and intra-regional movement, and social inequality at multiple scales: regional, site, and individual life courses, using isotopic, paleopathological, and geospatial methods. Talk title: Dismembering a Goddess: The Myth of Sati and her Sites of Powerīeth Scaffidi is an assistant professor of Anthropology & Heritage Studies at the University of California, Merced, and is a spatially-oriented anthropological bioarchaeologist. She curated the recent major exhibition, "Tantra: Enlightenment to Revolution." Her research interests revolve around the relationship between religion, politics and gender in South Asian visual culture. Imma Ramos is the curator of the medieval to modern South Asia collections at the British Museum in London. Drawing from art history, archaeology, and religious studies, speakers explore various cultural understandings about bodies and the body politic–in their dismembered, deconstructed or dissected forms–as expressions of identity, faith, and nationalism. From ancient Andean trophy heads to medieval Christian relics and Hindu pilgrimage sites in colonial Bengal, these talks examine the making and meaning of the body in pieces, from its metaphorical to very visceral fragmentation. This interdisciplinary panel focuses on fragmentation of the human body, including the use of body parts in ritual, myth, and religion. Register in advance for this online event.
