How do I search for a file with the date inside the filename? 1

[jdouthit]

I'm trying to check to see if a file exists with a filename something like dkout-YYYY-mm-dd.txt where the YYYY would be the year in 4 digits, mm the month in two digits, and dd be the day in two digits. I really don't have a clue as to how to format a file with a date. This program will run everyday so it will need to check for the current date inside the filename each day. Can anybody help me with this? Thanks in advance.

i use this to get the system time and write it into a char string:

  struct tm *timeptr;
  time_t clock;

  if ( time ( &clock ) != (time_t)-1 )
  {
    if ( timeptr = localtime ( &clock ) )
    {
      strftime ( text, 249, " %d/%m/%Y %H:%M:%S", timeptr );
    }
  }

What does the "text" stand for in the strftime function?

ah forgot to put that in

It is simply a character string i.e.

char text[249];
