Pantheios 写入外部文件

Pantheios write to extenal file

本文关键字：文件 外部 Pantheios      更新时间：2023-10-16

我环顾四周，找不到确切如何做到这一点的答案。我正在尝试使用 Pantheios 进行日志记录，我想写入外部文件（否则有什么意义）。我正在遵循提供的示例之一，但它似乎没有在任何地方制作日志文件。这是代码：

编辑：pantheios_be_file_setFilePath也返回-4（PANTHEIOS_INIT_RC_UNSPECIFIED_FAILURE），所以那是.....没有帮助

    #include "stdafx.h"
    #include <pantheios/pantheios.hpp> 
    #include <pantheios/implicit_link/core.h>
    #include <pantheios/implicit_link/fe.simple.h> 
    #include <pantheios/implicit_link/be.WindowsConsole.h>
    #include <pantheios/implicit_link/be.file.h>
    #include <pantheios/frontends/fe.simple.h>
    #include <pantheios/backends/bec.file.h>
    #include <pantheios/inserters/args.hpp>
    PANTHEIOS_EXTERN_C const PAN_CHAR_T PANTHEIOS_FE_PROCESS_IDENTITY[] = PANTHEIOS_LITERAL_STRING("LogTest");
    int _tmain(int argc, _TCHAR* argv[])
    {
        try
        {
            pantheios_be_file_setFilePath(PANTHEIOS_LITERAL_STRING("testlogforme.log"),  PANTHEIOS_BE_FILE_F_TRUNCATE, PANTHEIOS_BE_FILE_F_TRUNCATE, PANTHEIOS_BEID_ALL);

            pantheios::log(pantheios::debug, "Entering main(", pantheios::args(argc,argv, pantheios::args::arg0FileOnly), ")");
            pantheios::log_DEBUG("debug yo");
            pantheios::log_INFORMATIONAL("informational fyi");
            pantheios::log_NOTICE("notice me!");
            pantheios::log_WARNING("warning!!");
            pantheios::log_ERROR("error omg");
            pantheios::log_CRITICAL("critical!!!");
            pantheios::log_ALERT("alert mang");
            pantheios::log_EMERGENCY("EMERGENCY!!!!!");
            pantheios_be_file_setFilePath(NULL, PANTHEIOS_BEID_ALL);
            system("pause");
            return EXIT_SUCCESS;
        }
        catch(std::bad_alloc&)
        {
            pantheios::log_ALERT("out of memory");
        }
        catch(std::exception& x)
        {
            pantheios::log_CRITICAL("Exception: ", x);
        }
        catch(...)
        {
            pantheios::puts(pantheios::emergency, "Unexpected unknown error");
        }
        return EXIT_FAILURE;
    }

也许我没有调用方法，或者它没有保存到一个好的位置？

事实证明，Pantheios的一些例子是不正确的。即使您处于C++，您也需要调用 pantheios_init（）。这是我删除所有代码并实现一个有效的示例后开始工作的示例。

    // Headers for main()
    #include <pantheios/pantheios.hpp> 
    #include <pantheios/backends/bec.file.h> 
    // Headers for implicit linking
    #include <pantheios/implicit_link/core.h>
    #include <pantheios/implicit_link/fe.simple.h>
    #include <pantheios/implicit_link/be.file.h>
    PANTHEIOS_EXTERN_C const char PANTHEIOS_FE_PROCESS_IDENTITY[] = "testLOL";
    int main()
    {
        if(pantheios::pantheios_init() < 0)
        {
            return 1;
        }
        pantheios::log_NOTICE("log-1"); // save until log file set
        pantheios_be_file_setFilePath("mylogfile.log"); // sets log file; write "log-1" stmt
        pantheios::log_NOTICE("log-2"); // write "log-2" stmt
        pantheios_be_file_setFilePath(NULL); // close "mylogfile"

        pantheios::log_NOTICE("log-3"); // save until log file set
        pantheios_be_file_setFilePath("mylogfile2.log"); // sets log file; write "log-3" stmt
        pantheios::log_NOTICE("log-4"); // write "log-4" stmt
        //system("pause");
        return 0;
    } // closes "mylogfile2" during program closedown

我在堆栈溢出的不同帖子中找到了该示例，但就像我说的，内置示例不起作用。
