# process

类似 Node.js 的 process 全局的实现。

¥An implementation of a Node.js-like process global.

# 静态成员

¥Static members

```
const arch: string
```
表示编译二进制文件的 CPU 架构的字符串。wasm32 或 wasm64。

¥String representing the CPU architecture for which the binary was compiled. Either wasm32 or wasm64.
```
const platform: string
```
表示编译二进制文件的操作系统平台的字符串。总是 wasm。

¥String representing the operating system platform for which the binary was compiled. Always wasm.
```
const argv: string[]
```
实例化时传递给二进制文件的命令行参数数组。

¥Array of command line arguments passed to the binary upon instantiation.
```
const env: Map<string,string>
```
二进制文件用户环境中的变量映射。

¥Map of variables in the binary's user environment.
```
var exitCode: i32
```
进程正常退出时使用的进程退出代码。默认为 0。

¥Process exit code to use when the process exits gracefully. Defaults to 0.
```
function exit(code?: i32): void
```
使用给定的退出代码或 process.exitCode（如果省略）终止进程。

¥Terminates the process with either the given exit code, or process.exitCode if omitted.
```
const stdin: ReadableStream
const stdout: WritableStream
const stderr: WritableStream
```
流分别连接到 stdin (fd 0)、stdout (fd 1) 和 stderr (fd 2)。

¥Streams connected to stdin (fd 0), stdout (fd 1) and stderr (fd 2) respectively.
```
function time(): i64
```
获取系统当前时间（自 Unix 纪元以来的毫秒数）。

¥Obtains the system's current time of day, in milliseconds since Unix epoch.
```
function hrtime(): u64
```
获取系统的单调高解析时间，以纳秒为单位，自过去的任意时间开始。

¥Obtains the system's monotonic high resolution time, in nanoseconds since an arbitrary time in the past.
