4 The object type set to a null reference. 5 TypeName will return the name of the class of the object contained. The data would be an interface pointer, that is, a pointer to a pointer to a virtual method table (which is an array of function pointers).
This technique pertains to multitasking operating systems, and is sometimes called a subprocess or traditionally a subtask. There are two major procedures for creating a child process: the fork system call (preferred in Unix-like systems and the POSIX standard) and the spawn (preferred in the modern (NT) kernel of Microsoft Windows , as well as ...
Component Object Model (COM) is a binary-interface technology for software components from Microsoft that enables using objects in a language-neutral way between different programming languages, programming contexts, processes and machines.
Released in 1996, it is written in C++ and became an object oriented language. VBA 5.0 was launched in 1997 along with all of MS Office 97 products. The only exception for this was Outlook 97 which used VBScript. VBA 6.0 and VBA 6.1 were launched in 1999, notably with support for COM add-ins in Office 2000.
In Microsoft Windows applications programming, OLE Automation (later renamed to simply Automation [1] [2]) is an inter-process communication mechanism created by Microsoft.It is based on a subset of Component Object Model (COM) that was intended for use by scripting languages – originally Visual Basic – but now is used by several languages on Windows.
The names of members within passed structures and objects would also be considered part of the API, and not ABI. Sometimes APIs do include keywords to specify the calling convention for functions. Calling conventions do not typically include information on handling lifespan of dynamically-allocated structures and objects.
Then it uses a trusted send function to pass the message to a trusted OS process. The send function serves the same purpose as the trap; that is, it carefully checks the message, switches the processor to kernel mode, and then delivers the message to a process that implements the target functions. Meanwhile, the user process waits for the ...
Most modern implementations of a function call use a call stack, a special case of the stack data structure, to implement function calls and returns. Each procedure call creates a new entry, called a stack frame , at the top of the stack; when the procedure returns, its stack frame is deleted from the stack, and its space may be used for other ...
