Overview ¶
Package gproc implements communication and management of processes.
进程管理/通信, 本进程管理从syscall, os.StartProcess, exec.Cmd都使用过, 最后采用了exec.Cmd来实现多进程管理,这是一个顶层的跨平台封装,兼容性更好,另外两个是偏底层的接口。

向指定gproc进程发送数据 数据格式:总长度(24bit)|发送进程PID(24bit)|接收进程PID(24bit)|分组长度(8bit)|分组名称(变长)|校验(32bit)|参数(变长)
Types ¶
type Manager ¶
type Manager struct {
// contains filtered or unexported fields
}
进程管理器
func (*Manager) NewProcess ¶
创建一个进程(不执行)
type Process ¶
子进程
func NewProcess ¶
创建一个进程(不执行)
func (*Process) Release ¶
Release releases any resources associated with the Process p, rendering it unusable in the future. Release only needs to be called if Wait is not.
