libPhenom 是 Facebook 发布的一个高性能的C语言并发编程框架，支持事件驱动，支持多线程，还提供了内存管理和常用数据结构，甚至是json处理。

示例代码：

#include "phenom/defs.h"
#include "phenom/job.h"
#include "phenom/log.h"
#include "phenom/sysutil.h"

int main(int argc, char **argv)
{
  // Must be called prior to calling any other phenom functions
  ph_library_init();
  // Optional config file for tuning internals
  ph_config_load_config_file("/path/to/my/config.json");
  // Enable the non-blocking IO manager
  ph_nbio_init(0);

  // Do stuff here to register client/server stuff.
  // This enables a very simple request/response console
  // that allows you to run diagnostic commands:
  // `echo memory | nc -UC /tmp/phenom-debug-console`
  // The code behind this is in
  // https://github.com/facebook/libphenom/blob/master/corelib/debug_console.c
  ph_debug_console_start("/tmp/phenom-debug-console");

  // Run
  ph_sched_run();

  return 0;
}
