如何提取文件日期？

[javaduke]

用到那个WindowsAPI或者ShellAPI?

CTime::GetData()

[memset]

可以用_stat函数

[prog_st]

/* STAT.C: This program uses the _stat function to
* report information about the file named STAT.C.
*/

#include <time.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>

void main( void )
{
struct _stat buf;
int result;
char buffer[] = "A line to output";

/* Get data associated with "stat.c": */
result = _stat( "stat.c", &buf );

/* Check if statistics are valid: */
if( result != 0 )
perror( "Problem getting information" );
else
{
/* Output some of the statistics: */
printf( "File size : %ld\n", buf.st_size );
printf( "Drive : %c:\n", buf.st_dev + 'A' );
printf( "Time modified : %s", ctime( &buf.st_atime ) );
}
}


Output

File size : 745
Drive : C:
Time modified : Tue May 03 00:00:00 1994

使用_stat函数可以获取create modified access的时间。
Example
/* stat.c: This program uses the _stat64 function to
* report information about the file named stat.c.
*/

#include <time.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>

void main( void )
{
struct __stat64 buf;
int result;
char buffer[] = "A line to output";

/* Get data associated with "stat.c": */
result = _stat64( "stat.c", &buf );

/* Check if statistics are valid: */
if( result != 0 )
perror( "Problem getting information" );
else
{
/* Output some of the statistics: */
printf( "File size : %ld\n", buf.st_size );
printf( "Drive : %c:\n", buf.st_dev + 'A' );
printf( "Time modified : %s", _ctime64( &buf.st_mtime ) );
}
}


Output
File size : 865
Drive : C:
Time modified : Fri Jan 22 07:44:56 1999
