Qt下如何修改文件的时间（全平台修改）

提供一个全平台修改文件的时间的方法,希望大家喜欢

/* UTIME.C: This program uses _utime to set the

 * file-modification time to the current time.

 * utime.c is a file you should change it by yourself

 */

#include <stdio.h>

#include <stdlib.h>

#include <sys/types.h>

#ifdef WIN32

#include <sys/utime.h>

#define SHOWCMD "dir utime.c"

#else

#define _utime utime

#define _utimbuf utimbuf

#include <utime.h>

#define SHOWCMD "ls -l utime.c"

#endif

void main( void )

{

   /* Show file time before and after. */

   system( SHOWCMD );

   if( _utime( "utime.c", NULL ) == -1 )

      perror( "_utime failed\n" );

   else

      printf( "File time modified\n" );

   system( SHOWCMD );

}
