subprocess.signalCode | Node.js API 文档

subprocess.signalCode 属性表示子进程接收到的信号（如果有），否则为 null。

🌐 The subprocess.signalCode property indicates the signal received by the child process if any, else null.

当子进程被信号终止时，subprocess.exitCode 将为 null。要获取对应的 POSIX 退出码，请使用 util.convertProcessSignalToExitCode(subprocess.signalCode)。

🌐 When the child process is terminated by a signal, subprocess.exitCode will be null. To get the corresponding POSIX exit code, use util.convertProcessSignalToExitCode(subprocess.signalCode).
