Restarts are functions closed over some lexical environment, allowing the programmer to repair this environment before exiting the condition handler completely or unwinding the stack even partially. An example is the ENDPAGE condition in PL/I; the ON unit might write page trailer lines and header lines for the next page, then fall through to ...
It is okay for your explanation to be quite short. For example, if you are making a spelling correction, you might just put "fix typo". If you've made a minor change that should be uncontroversial, such as a spelling or grammar correction, you can check the "☑ This is a minor edit" box. Minor edits are those that do not modify the meaning of ...
A checksum of a message is a modular arithmetic sum of message code words of a fixed word length (e.g., byte values). The sum may be negated by means of a ones'-complement operation prior to transmission to detect unintentional all-zero messages.
PHP provides a file-based locking [17] as well as a Mutex class in the pthreads extension. [18] Python provides a low-level mutex mechanism with a Lock class from the threading module. [19] The ISO/IEC Fortran standard (ISO/IEC 1539-1:2010) provides the lock_type derived type in the intrinsic module iso_fortran_env and the lock/unlock ...

Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile. [17]
Rather, it is a description or a template for solving a particular type of problem that can be deployed in many different situations. [2] Design patterns can be viewed as formalized best practices that the programmer may use to solve common problems when designing a software application or system.
To prevent code injection problems, the person could use secure input and output handling strategies, such as: Using an application programming interface that, if used properly, is secure against all input characters. Parameterized queries allow the moving of user data out of a string to be interpreted.
