Pantheios write to extenal file - c++

Question

I looked around and I couldn't find the answer to how exactly to do this. I am trying to use Pantheios for logging and I want to write to an external file (otherwise whats the point). I am following one of the examples provided but It doesn't seem to be making the log file anywhere. Here is the code:
Edit: Also pantheios_be_file_setFilePath is returning -4 (PANTHEIOS_INIT_RC_UNSPECIFIED_FAILURE) so thats.....not helpful
#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;
}
Maybe I'm not calling a method or maybe its not being saved to a good location?

It turns out that some of the examples out there for pantheios are incorrect. You DO need to call pantheios_init() even if you are in C++. Here Is the example I got to work after deleting all my code and implementing an example that works.
// 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
I found the example on a different post on stack overflow but like I said, the built in examples do not work.
