Get a File Time
以下的範例示範如何用 c 取得一個檔案的建立時間
#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>
void main( void )
{
struct _stat buf;
int result;
struct tm when;
/* Get data associated with "stat.c": */
result = _stat( "filetime.c", &buf );
/* Check if statistics are valid: */
if( result != 0 )
perror( "Problem getting information" );
else
{
when = *localtime( &buf.st_ctime );
/* 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_ctime ) );
//取得個別時間成份
printf("Year:%d\n", when.tm_year + 1900);
printf("Month:%d\n", when.tm_mon + 1);
printf("Day:%d\n", when.tm_mday);
printf("Hour:%d\n", when.tm_hour);
printf("Minute:%d\n", when.tm_min);
printf("Second:%d\n", when.tm_sec);
}
}
若要取得「最後存取時間」,將「buf.st_ctime」改成「buf.st_atime」;
若要取得「最後修改時間」,將「buf.st_ctime」改成 「buf.st_mtime」。
