Function Documentation

◆ memory_backend_create()

void * memory_backend_create ( void )

Create memory backend instance.

Returns: Backend instance or NULL on failure

  memory_backend_t *backend = SAFE_MALLOC(sizeof(memory_backend_t), memory_backend_t *);
  if (!backend) {
    log_error("Failed to allocate memory backend");
