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。
二、例子

简单的例子

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; }
