  2. Stack-based memory allocation - Wikipedia

    en.wikipedia.org/wiki/Stack-based_memory_allocation

    The stack is often used to store variables of fixed length local to the currently active functions. Programmers may further choose to explicitly use the stack to store local data of variable length. If a region of memory lies on the thread's stack, that memory is said to have been allocated on the stack, i.e. stack-based memory allocation (SBMA).

  3. C dynamic memory allocation - Wikipedia

    en.wikipedia.org/wiki/C_dynamic_memory_allocation

    The C programming language manages memory statically, automatically, or dynamically.Static-duration variables are allocated in main memory, usually along with the executable code of the program, and persist for the lifetime of the program; automatic-duration variables are allocated on the stack and come and go as functions are called and return.

  4. Static variable - Wikipedia

    en.wikipedia.org/wiki/Static_variable

    In computer programming, a static variable is a variable that has been allocated "statically", meaning that its lifetime (or "extent") is the entire run of the program. This is in contrast to shorter-lived automatic variables, whose storage is stack allocated and deallocated on the call stack; and in contrast to dynamically allocated objects, whose storage is allocated and deallocated in heap ...

  5. Garbage collection (computer science) - Wikipedia

    en.wikipedia.org/wiki/Garbage_collection...

    If a function-local allocation is found to be accessible to another function or thread, the allocation is said to "escape" and cannot be done on the stack. Otherwise, the object may be allocated directly on the stack and released when the function returns, bypassing the heap and associated memory management costs. [22]

  6. Funarg problem - Wikipedia

    en.wikipedia.org/wiki/Funarg_problem

    Apple has proposed and implemented a closure syntax for C that solves the upwards funarg problem by dynamically moving closures from the stack to the heap as necessary. [ citation needed ] The Java programming language deals with it by requiring that context used by nested functions in anonymous inner and local classes be declared final , and ...

  7. Stack trace - Wikipedia

    en.wikipedia.org/wiki/Stack_trace

    In computing, a stack trace (also called stack backtrace [1] or stack traceback [2]) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places: the stack and the heap. Memory is continuously allocated on a stack but not on a ...

  8. Variable-length array - Wikipedia

    en.wikipedia.org/wiki/Variable-length_array

    The GNU Compiler Collection (GCC) for C allocates memory for VLAs with automatic storage duration on the stack. [5] This is the faster and more straightforward option compared to heap-allocation, and is used by most compilers. VLAs can also be allocated on the heap and internally accessed using a pointer to this block.

  9. Region-based memory management - Wikipedia

    en.wikipedia.org/wiki/Region-based_memory_management

    Like stack allocation, regions facilitate allocation and deallocation of memory with low overhead; but they are more flexible, allowing objects to live longer than the stack frame in which they were allocated. In typical implementations, all objects in a region are allocated in a single contiguous range of memory addresses, similarly to how ...
