I am trying to use pantheios file stock back end to log from my dll in c++. The file gets created but nothing gets written to the file.
Here is a snippet of my code

if (pantheios::pantheios_init() < 0)
{    
   MessageBox(NULL, "Init Failed", "fvm", MB_OK);
}else {
   MessageBox(NULL, "Init Passed", "fvm", MB_OK);
   pantheios::log_INFORMATIONAL("Logger enabled!");
}

DWORD pid = GetCurrentProcessId();
sprintf_s(moduleName, sizeof(moduleName), "C:\\%d.log", pid);
pantheios_be_file_setFilePath(moduleName, PANTHEIOS_BE_FILE_F_TRUNCATE,PANTHEIOS_BE_FILE_F_TRUNCATE, PANTHEIOS_BEID_LOCAL);
pantheios::log(pantheios::debug, "Entering main");

I get the Init Passed message box but no log statements are dumped in the file.
