崩溃堆栈，为什么会出错。
mysql C版本为 6.0.2
运行不了多久就崩溃了。。。。刚开始是好好的，我还以为是SQL语句有问题，我打印出来直接放到工具里面运行很正常啊。。。为什么崩溃了呢？
代码如下:
DataBase_IsErrorOccur = FALSE;
NETDATABASE_MYSQLHANDLE st_hDatabaseMySQL;
memset(&st_hDatabaseMySQL,'\0',sizeof(st_hDatabaseMySQL));
if (!m_hNetComponents.NetEngine_LibHandleEx_Get(xhNet,&st_hDatabaseMySQL))
{
return FALSE;
}
//撤消自动提交模式
if (0 != mysql_autocommit(&st_hDatabaseMySQL.st_MySQL,FALSE))
{
DataBase_IsErrorOccur = TRUE;
DataBase_dwErrorCode = ERROR_HELPCOMPONENTS_DATABASE_MYSQL_EXEC_CANCEAUTOCOMMIT;
return FALSE;
}
//执行SQL语句
if (0 != mysql_query(&st_hDatabaseMySQL.st_MySQL,lpszSQLQuery))
{
printf("数据库查询错误：%s,SQL语句：%s\n",mysql_error(&st_hDatabaseMySQL.st_MySQL),lpszSQLQuery);
DataBase_IsErrorOccur = TRUE;
DataBase_dwErrorCode = ERROR_HELPCOMPONENTS_DATABASE_MYSQL_EXEC_ISFAILED;
return FALSE;
}
//如果没有成功
if (0 != mysql_commit(&st_hDatabaseMySQL.st_MySQL))
{
//回滚事务
mysql_rollback(&st_hDatabaseMySQL.st_MySQL);
mysql_autocommit(&st_hDatabaseMySQL.st_MySQL,TRUE);
DataBase_IsErrorOccur = TRUE;
DataBase_dwErrorCode = ERROR_HELPCOMPONENTS_DATABASE_MYSQL_EXEC_COMMIT;
return FALSE;
}
//恢复自动提交模式
if (0 != mysql_autocommit(&st_hDatabaseMySQL.st_MySQL,TRUE))
{
DataBase_IsErrorOccur = TRUE;
DataBase_dwErrorCode = ERROR_HELPCOMPONENTS_DATABASE_MYSQL_EXEC_AUTOCOMMIT;
return FALSE;
}
return TRUE;
崩溃如下所示

[解决办法]
自己malloc后ptr为空？

[解决办法]
……不太清楚了...gdb调试吧
