C process control refers to a group of functions in the standard library of the C programming language implementing basic process control operations. [1] [2] The process control operations include actions such as termination of the program with various levels of cleanup, running an external command interpreter or accessing the list of the environment operations.
In the C Standard Library, signal processing defines how a program handles various signals while it executes. A signal can report some exceptional behavior within the program (such as division by zero), or a signal can report some asynchronous event outside the program (such as someone striking an interactive attention key on a keyboard).
When a child process terminates, it becomes a zombie process, and continues to exist as an entry in the system process table even though it is no longer an actively executing program. Under normal operation it will typically be immediately waited on by its parent, and then reaped by the system, reclaiming the resource (the process table entry).
A web page and its JavaScript typically run in a single-threaded web browser process. The browser process deals with messages from a queue one at a time. A JavaScript function or another browser event might be associated with a given message. When the browser process has finished with a message, it proceeds to the next message in the queue.
The SIGTRAP signal is sent to a process when an exception (or trap) occurs: a condition that a debugger has requested to be informed of – for example, when a particular function is executed, or when a particular variable changes value. SIGURG The SIGURG signal is sent to a process when a socket has urgent or out-of-band data available to read.
process.h is the C header file which contains function declarations and macros used in working with threads and processes. Most C compilers that target DOS , Windows 3.1x , Win32 , OS/2 , Novell NetWare or DOS extenders supply this header and the library functions in their C library.
In computing and computer programming, exception handling is the process of responding to the occurrence of exceptions – anomalous or exceptional conditions requiring special processing – during the execution of a program.
Such an orphan process becomes a child of a special root process, which then waits for the child process to terminate. Likewise, a similar strategy is used to deal with a zombie process, which is a child process that has terminated but whose exit status is ignored by its parent process. Such a process becomes the child of a special parent ...
