mongodb c driver

mongodb的c driver,源码在

一、编译

http://api.mongodb.org/c/current/building.html

linux、mac、windows-cygwin下,下载scons,

http://www.scons.org/,使用python setup.py install安装scons,

然后去mongodb驱动源码下,scons安装驱动,即可。

比如windows下自动生成bson.dll和mongoc.dll。

Connecting这一节的例子有点问题:

1、status没有定义类型,

2、MONGO_CONN_BAD_ARG这个常量已经在新版本里去掉了,

例子可以改为:

#include <stdio.h>
#include "mongo.h"

int main() {
  mongo conn[1];
  int status;
  status = mongo_connect( conn, "127.0.0.1", 27017 );

  if( status != MONGO_OK ) {
      switch ( conn->err ) {
        case MONGO_CONN_SUCCESS:    printf( "connection succeeded\n" ); break;
        //case MONGO_CONN_BAD_ARG:    printf( "bad arguments\n" ); return 1;
        case MONGO_CONN_NO_SOCKET:  printf( "no socket\n" ); return 1;
        case MONGO_CONN_FAIL:       printf( "connection failed\n" ); return 1;
        case MONGO_CONN_NOT_MASTER: printf( "not master\n" ); return 1;
      }
  }else{
  	  printf( "MONGO_OK:connection succeeded\n%d\n", status );
  }
  
  mongo_destroy( conn );

  return 0;
}
