Morning,

First of all, thanks again Ioannis and Jason for the suggestions.

Secondly, I figured if anyone were interested, below is how I solved
this time stamp problem.  It is not portable to a Unix/Unix-based
platform, but since the job on my end runs on an NT platform...it serves
the purpose that I need it to serve.

/*DATE STAMP TEST PROGRAM*/

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main()
{
  FILE*      testfile ;
 

   char*      PtrToFname ; 

Not needed

 
  char       FileName[27] ;
  time_t     CurTime ;
  struct tm* datetime ;

  CurTime = time( NULL ) ;
  datetime = localtime( &CurTime ) ;

  strftime( FileName, 27, "C:\\temp\\hsloan%Y%m%d.txt", datetime ) ;

  printf( "%s", FileName ) ;

  PtrToFname = FileName ; 

Not needed 

 

   testfile = fopen( PtrToFname, "w" ) ;
  if( testfile == NULL )
  {
    printf( "\nUNABLE TO CREATE OUTPUT FILE! (ABNORMAL TERMINATION)\n" )
;
    exit( 0 ) ;
  }

  fclose( testfile ) ;

  return 0 ;
}

Thanks again everyone.

So the program becomes:
 
/*DATE STAMP TEST PROGRAM*/
 
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
 
int main(void)
{
  FILE*      testfile ;
  char       FileName[27] ;
  time_t     CurTime ;
  struct tm* datetime ;
 
  CurTime = time( NULL ) ;
  datetime = localtime( &CurTime ) ;
 
  strftime( FileName, 27, "C:\\temp\\hsloan%Y%m%d.txt", datetime ) ;
 
  printf( "%s", FileName ) ;
 
  testfile = fopen( FileName, "w" ) ;
  if( testfile == NULL )
  {
    printf( "\nUNABLE TO CREATE OUTPUT FILE! (ABNORMAL TERMINATION)\n" )
;
    exit( 0 ) ;
  }
 
  fclose( testfile ) ;
 
  return 0 ;
}

 
The program should be portable to UNIX too given that you provide the
correct path syntax (/ for directories). Also why provide path anyway?
(it will be created in the current path where the program is excuted).
