In computer programming, DLL injection is a technique used for running code within the address space of another process by forcing it to load a dynamic-link library. [1] DLL injection is often used by external programs to influence the behavior of another program in a way its authors did not anticipate or intend.
Microsoft Windows library files. The Microsoft Windows operating system supports a form of shared libraries known as "dynamic-link libraries", which are code libraries that can be used by multiple processes while only one copy is loaded into memory. This article provides an overview of the core libraries that are included with every modern ...
The LIB file (import library) is used to link against a DLL at compile-time; it is not necessary for run-time linking. Unless the DLL is a Component Object Model (COM) server, the DLL file must be placed in one of the directories listed in the PATH environment variable, in the default system directory, or in the same directory as the program ...
Position-independent code. In computing, position-independent code[ 1] ( PIC[ 1]) or position-independent executable ( PIE) [ 2] is a body of machine code that executes properly regardless of its memory address. [ a] PIC is commonly used for shared libraries, so that the same library code can be loaded at a location in each program's address ...
Dynamic linker. In computing, a dynamic linker is the part of an operating system that loads and links the shared libraries needed by an executable when it is executed (at "run time"), by copying the content of libraries from persistent storage to RAM, filling jump tables and relocating pointers. The specific operating system and executable ...
DLL Hell. In computing, DLL hell is a term for the complications that arise when one works with dynamic-link libraries (DLLs) used with Microsoft Windows operating systems, [ 1] particularly legacy 16-bit editions, which all run in a single memory space. DLL hell can manifest itself in many different ways wherein applications neither launch nor ...
In computer science, a pointer is an object in many programming languages that stores a memory address. This can be that of another value located in computer memory, or in some cases, that of memory-mapped computer hardware. A pointer references a location in memory, and obtaining the value stored at that location is known as dereferencing the ...
Stack-based memory allocation. A typical stack, storing local data and call information for nested procedure calls (not necessarily nested procedures ). This stack grows downward from its origin. The stack pointer points to the current topmost datum on the stack. A push operation decrements the pointer and copies the data to the stack; a pop ...
