The raise(3) library function sends the specified signal to the current process. Exceptions such as division by zero, segmentation violation , and floating point exception will cause a core dump and terminate the program. The kernel can generate signals to notify processes of events.
C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions.
Some systems and programming languages allow user subroutines to be registered so that they are invoked at program termination before the process actually terminates for good. As the final step of termination, a primitive system exit call is invoked, informing the operating system that the process has terminated and allows it to reclaim the ...
An end of interrupt (EOI) is a computing signal sent to a programmable interrupt controller (PIC) to indicate the completion of interrupt processing for a given interrupt. Interrupts are used to facilitate hardware signals sent to the processor that temporarily stop a running program and allow a special program, an interrupt handler, to run ...
A service interface in SOP is an in-memory object that describes a well-defined software task with well-defined input and output data structures. Service interfaces can be grouped into packages. An SOP service interface can be externalized as a WSDL operation and a single service or a package of services can be described using WSDL. Furthermore ...
In computing, a crash, or system crash, occurs when a computer program such as a software application or an operating system stops functioning properly and exits. On some operating systems or individual applications, a crash reporting service will report the crash and any details relating to it (or give the user the option to do so), usually to ...
This program is one of all the programs on which the halting function h is defined. The next step of the proof shows that h(e,e) will not have the same value as f(e,e). It follows from the definition of g that exactly one of the following two cases must hold: f(e,e) = 0 and so g(e) = 0. In this case program e halts on input e, so h(e,e) = 1.
The sentinel value is a form of in-band data that makes it possible to detect the end of the data when no out-of-band data (such as an explicit size indication) is provided. The value should be selected in such a way that it is guaranteed to be distinct from all legal data values since otherwise, the presence of such values would prematurely ...
