可以看到,types[]是mysql_type_info种的一个静态数组,让我们来看一下对应的cpp文件中的定义。 顺便说一句,sql_tinyint,sql_decimal等都被typedef了(在sql_types.h中),例如sql_tinyint_unsigned其实就是tiny_int<uint8_t>,而sql_int其实就是MYSQL C API所定义的int32_
Theset::find() functionis a predefined function, it is used to check whether an element belong to the set or not, if element finds in the set container it returns an iterator pointing to that element. The function checks whether an element belong to the set or not. If an element belong...

set(openssl_root /workspace/xxx/openssl-1.1.1v/out) file(GLOB openssl_libs ${openssl_root}/lib*/*.so) include_directories( ${openssl_root}/include ) 当然,为了避免多个库文件,链接出错的问题,最好单独自己编译Find_xxxx.cmake文件,然后在主CmakeLists.txt中include。

简单来说就是math.hpp里定义了加法函数和减法函数,main.cpp里调用了这两个函数进行测试。 我们主要看CMakeLists.txt的内容: cmake_minimum_required(VERSION 3.10) project(course_07) set(INCLUDE "include") #set(CMAKE_INSTALL_PREFIX ${CMAKE_CURRENT_LIST_DIR}/install) add_library(add) target_sou...
