Text file name saved as current date and time?

I have a program with needs to contain the system's date and time as a text file name for a flat file that the C++ program creates (ex:  20070402134525.txt)

I've already got the program pulling the system date and time (see below.)  I just need to know how I can get that information in to the file name.

char buffer[SIZE];
time_t curtime;
struct tm *loctime;
     
// Get the current time.
curtime = time (NULL);
     
// Convert it to local time representation.
loctime = localtime (&curtime);
         
 //Date and time format
 strftime (buffer, SIZE, "%Y%m%d%H%M%S", loctime);

You can create a file with that name like

#include <stdio.h>

FILE* p = fopen(buffer,"w"); // file name is in 'buffer'

or

#include <fstream>
using namespace std;

ofstream os(buffer); // file name is in 'buffer'

Which method are you using to open the file?

I'm using:  #include <stdio.h>

I've got the file going to a testing file called "651_GBI.txt."  Once I put it in to production, they'll be sending the flat file about every thrity minutes.  So, I'll need it to save the flat file as "new" each time and not write over the previous copy.

Here's where I'm sending my test file.
FILE *file = fopen("y:\\incoming\\oss\\down\\651_GBI.txt", "r");

Then make that like

char buffer[SIZE];
time_t curtime;
struct tm *loctime;
     
// Get the current time.
curtime = time (NULL);
     
// Convert it to local time representation.
loctime = localtime (&curtime);
         
 //Date and time format
 strftime (buffer, SIZE, "%Y%m%d%H%M%S", loctime);

char path[MAX_PATH];

sprintf(path,"y:\\incoming\\oss\\down\\%s.txt", buffer);

FILE *file = fopen(path, "w"); // 'w' for write access
