使用v140_xp
作为Platform Toolset
(目标Win32)运行使用Visual C ++ 2015 Express编译的以下example for _stat from MSDN在Windows 7上正常运行,但在我测试的几台计算机上运行时不在Windows XP上运行。 / p>
// crt_stat.c
// This program uses the _stat function to
// report information about the file named crt_stat.c.
#include <time.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>
#include <errno.h>
int main()
{
struct _stat buf;
int result;
char timebuf[26];
char* filename = "crt_stat.c"; // Absolute paths like "D:\\crt_stat.c" produce the same behaviour.
errno_t err;
// Get data associated with "crt_stat.c":
result = _stat( filename, &buf );
// Check if statistics are valid:
if ( result != 0 )
{
perror( "Problem getting information" );
switch ( errno )
{
case ENOENT:
printf( "File %s not found.\n", filename );
break;
case EINVAL:
printf( "Invalid parameter to _stat.\n" );
break;
default:
/* Should never be reached. */
printf( "Unexpected error in _stat.\n" );
}
}
else
{
// Output some of the statistics:
printf( "File size : %ld\n", buf.st_size );
printf( "Drive : %c:\n", buf.st_dev + 'A' );
err = ctime_s( timebuf, 26, &buf.st_mtime );
if ( err )
{
printf( "Invalid arguments to ctime_s." );
return 1;
}
printf( "Time modified : %s", timebuf );
}
}
Windows 7输出:
File size : 6
Drive : D:
Time modified : Tue Sep 8 10:06:57 2015
Windows XP输出:
Problem getting information: Invalid argument
Invalid parameter to _stat.
是的,crt_stat.c位于可执行文件目录中,也是CWD。 p>
这是一个Bug还是我错过了什么?
答案 0 :(得分:5)
正如评论中所指出的,它在运行时中是bug。目前(2015-09-09)该修补程序尚未在更新中提供,但可能很快就会提供。解决方法是改为使用GetFileAttributesEx
。

在Visual Studio 2015 Update 1的Visual C ++ Redistributable上解决了该错误
