Saving file down in date format

[Helfenmir]

Hi
I need to change a file name and save it down in a different folder with the current date as determined by the system clock ie. <date>.txt the date format needs to be YYMMDD. Can anyone help me please.

Many Thanks
Helfenmir

Hi,

try with:

#include <time.h>

struct tm *pnow ;
long tnow ; /* or time_t, see your doc */
FILE *stream ;
char fullname[80];
......

time( &tnow ) ;
pnow = localtime( &tnow ) ; // see difference with gmtime
// the area tm is internal at
// the system function

sprintf( fullname, &quot;%s%02d%02d%02d.txt&quot;,
&quot;mypath&quot;, // warning at / or \\ if unix or dos
pnow->tm_year - 1900, // warining at millenium bug ??
pnow->tm_mon + 1, // Jan = 0 ??
pnow->tm_day ) ;

stream = fopen( fullname, &quot;w&quot; ) ; // test
fclose( stream );

-------

However, see doc in your implementation, for types and
include files, and resolve the millenium bug.


Bye
