In the field of computer science, the term reentrant is used to describe a type of code that can be safely executed by multiple threads or processes simultaneously, without causing unexpected behavior or errors. This is achieved by ensuring that each thread or process has its own copy of any variables or data that the code uses, rather than sharing a single copy between them. This allows the code to be executed in a way that is both efficient and safe, without the risk of data corruption or other issues that can arise when multiple threads or processes attempt to access the same data simultaneously. One common example of reentrant code is the use of recursive functions, which are functions that call themselves repeatedly in order to solve a problem. Because each recursive call creates a new instance of the function with its own set of variables and data, the code can be executed safely and efficiently by multiple threads or processes at the same time. Another example of reentrant code is interrupt service routines, which are used in many electronic devices to handle hardware events such as button presses or sensor readings. These routines must be able to execute quickly and without interruption, and are designed to be reentrant so that they can be safely called from multiple threads or processes simultaneously. Overall, the concept of reentrancy is an important one in computer science, as it allows developers to write code that is both efficient and safe in a multi-threaded or multi-process environment. By ensuring that each thread or process has its own copy of any data that the code uses, reentrant code can be executed without the risk of data corruption or other issues that can arise when multiple threads or processes attempt to access the same data simultaneously.

Reentrant, within the context of architecture, is an architectural feature that protrudes from the inner portion of a building or structure, creating a void in the middle. This feature can be seen in a variety of buildings and structures, from historical fortifications and city walls to modern office buildings. Reentrant features can be either decorative or functional, with the latter providing additional space for an outdoor space or an outdoor room. Additionally, the reentrant feature may also provide additional structural strength when used in a structural capacity.

Masonry architecture is a form of construction that has been used since ancient times. It is a system of forming walls and other structures from individual units of materials such as stone, brick, concrete, and mortar. Reentrant is a term used to describe masonry walls that have more than one corner, creating a concave or convex shape. This type of wall is also referred to as a 'curvilinear' wall because its shape is not linear. The reentrant wall is both aesthetically pleasing and structurally sound as it can provide additional strength and stability to the structure.
