priority_queue is relatively simple to use for basic types. His template declaration has three parameters, type is the data type, Container is the container that holds the data, functional is the element comparison method. Container must be an array-

Precompilation is the first step in the entire compilation process and is the result of the g++-e option output. This step deals with the macros in the source file/header file, which are commonly used in the following categories: file contains:

In a System v-like environment, one has the type ucontext_t defined in and the four functions Text (2), SetContext (2), Makecontext () and Swapcontext (), allow user-level context switching between multi-ple Control within a process. In the System

system call:is a set of interfaces that the operating system interacts with for user-state processes and hardware devices (such as CPUs, disks, printers, and so on), that is, an interface layer that is set between applications and hardware devices.
