In programming, void is a keyword used to declare a function that does not return any value. It is also used to declare a pointer that points to an unknown type, often seen in generic programming. For example, in C and C-derived languages:
uint32_t x, y; // Linear search through the labyrinth using atomic hints for (int i = 0; i < maze->width * maze->height; i++) // Convert linear index to 2D coordinates x = i % maze->width; y = i / maze->width; // Attempt to atomically claim this page // exclusive: only if the current flag is FREE (0) if (atomic_compare_exchange(&maze->page_map[y * maze->width + x], 0, ALLOCATED)) // mark exclusive (owner thread ID stored elsewhere) maze->exclusive_owner[i] = get_current_thread_id(); return maze->pages[y * maze->width + x]; define labyrinth void allocpagegfpatomic exclusive
Whenever possible, allocate memory during driver initialization or in a process context before entering atomic, locked, or interrupt loops. In programming, void is a keyword used to
: Stands for "allocate page," which means reserving a specific block of memory. : Stands for "allocate page," which means reserving
The keyword define labyrinth void allocpagegfpatomic exclusive is not a valid C statement, but it is a powerful . It defines a set of constraints:
