Thread: interpreting time fields in a structure

Anyone know how to interpret the time fields in the _finddata_t structure. I searched msdn but it curiously wasnt any help. Im using Visual C++

Found this just by typing _finddata_t into the search box for MSDN. It relates to information returned from the _findfirst/_findnext set of functions.

Code:

The _finddata_t structure includes the following elements:

unsigned attrib

    File attribute

time_t time_create

    Time of file creation ( –1L for FAT file systems)

time_t time_access

    Time of last file access (–1L for FAT file systems)

time_t time_write

    Time of last write to file

_fsize_t size

    Length of file in bytes

char name[_MAX_FNAME]

    Null-terminated name of matched file/directory, without the path

In file systems that do not support the creation and last access
times of a file, such as the FAT system, the time_create and 
time_access fields are always –1L.

_MAX_FNAME is defined in STDLIB.H as 256 bytes.

Example

/* FFIND.C: This program uses the 32-bit _find functions to print
 * a list of all files (and their attributes) with a .C extension
 * in the current directory.
 */

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

void main( void )
{
    struct _finddata_t c_file;
    long hFile;

    /* Find first .c file in current directory */
    if( (hFile = _findfirst( "*.c", &c_file )) == -1L )
       printf( "No *.c files in current directory!\n" );
   else
   {
            printf( "Listing of .c files\n\n" );
            printf( "\nRDO HID SYS ARC  FILE         DATE %25c SIZE\n", ' ' );
            printf( "--- --- --- ---  ----         ---- %25c ----\n", ' ' );
            printf( ( c_file.attrib & _A_RDONLY ) ? " Y  " : " N  " );
            printf( ( c_file.attrib & _A_SYSTEM ) ? " Y  " : " N  " );
            printf( ( c_file.attrib & _A_HIDDEN ) ? " Y  " : " N  " );
            printf( ( c_file.attrib & _A_ARCH )   ? " Y  " : " N  " );
            printf( " %-12s %.24s  %9ld\n",
               c_file.name, ctime( &( c_file.time_write ) ), c_file.size );

            /* Find the rest of the .c files */
            while( _findnext( hFile, &c_file ) == 0 )
            {
                printf( ( c_file.attrib & _A_RDONLY ) ? " Y  " : " N  " );
                printf( ( c_file.attrib & _A_SYSTEM ) ? " Y  " : " N  " );
                printf( ( c_file.attrib & _A_HIDDEN ) ? " Y  " : " N  " );
                printf( ( c_file.attrib & _A_ARCH )   ? " Y  " : " N  " );
                printf( " %-12s %.24s  %9ld\n",
                   c_file.name, ctime( &( c_file.time_write ) ), c_file.size );
            }

       _findclose( hFile );
   }
}


Output

Listing of .c files

RDO HID SYS ARC  FILE         DATE                           SIZE
--- --- --- ---  ----         ----                           ----

Looks to me like you need to use the ctime functions on that info.

rofl, I didnt scroll down to the bottom the page Thanks.
