1：进入ChromeMain()函数，该函数在\chrome\app\chrome_main.cc

2：在ChromeMain()函数中，调用ContentMain()，该函数在\content\app\content_main.cc

3：在ContentMain（）中调用int Run()，该函数在\content\app\content_main_runner.cc中

4：在Run()中调用RunNamedProcessTypeMain（），根据命令行参数调用该函数创建其他进程。该函数在\content\app\content_main_runner.cc

int Run() override {
DCHECK(is_initialized_);
DCHECK(!is_shutdown_);
const base::CommandLine& command_line =
*base::CommandLine::ForCurrentProcess();
std::string process_type =
command_line.GetSwitchValueASCII(switches::kProcessType);

base::HistogramBase::EnableActivityReportHistogram(process_type);

MainFunctionParams main_params(command_line);
main_params.ui_task = ui_task_;
#if defined(OS_WIN)
main_params.sandbox_info = &sandbox_info_;
#elif defined(OS_MACOSX)
main_params.autorelease_pool = autorelease_pool_.get();
#endif

return RunNamedProcessTypeMain(process_type, main_params, delegate_);
}
