CFile::GetStatus

  • 项目

BOOLGetStatus(CFileStatus&rStatus)const;

staticBOOLPASCALGetStatus(LPCTSTRlpszFileName**,CFileStatus&rStatus);**

Return Value

TRUE if the status information for the specified file is successfully obtained; otherwise, FALSE.

Parameters

rStatus

A reference to a user-supplied CFileStatus structure that will receive the status information. The CFileStatus structure has the following fields:

  • CTime m_ctime   The date and time the file was created.

  • CTime m_mtime   The date and time the file was last modified.

  • CTime m_atime   The date and time the file was last accessed for reading.

  • LONG m_size   The logical size of the file in bytes, as reported by the DIR command.

  • BYTE m_attribute   The attribute byte of the file.

  • char m_szFullName[_MAX_PATH]   The absolute filename in the Windows character set.

lpszFileName

A string in the Windows character set that is the path to the desired file. The path can be relative or absolute, but cannot contain a network name.

Remarks

The virtual version of GetStatus retrieves the status of the open file associated with this CFile object. It does not insert a value into the m_szFullName structure member.

The static version gets the status of the named file and copies the filename to m_szFullName. This function obtains the file status from the directory entry without actually opening the file. It is useful for testing the existence and access rights of a file.

The m_attribute is the file attribute. The Microsoft Foundation classes provide an enum type attribute so that you can specify attributes symbolically:

enum Attribute {
   normal =    0x00,
   readOnly =  0x01,
   hidden =    0x02,
   system =    0x04,
   volume =    0x08,
   directory = 0x10,
   archive =   0x20
   };

Example

//example for CFile::GetStatus
CFileStatus status;
extern CFile cfile;
if( cfile.GetStatus( status ) )    // virtual member function
   {
      #ifdef _DEBUG
         afxDump << "File size = " << status.m_size << "\n";
      #endif
   }
char* pFileName = "test.dat";
if( CFile::GetStatus( pFileName, status ) )   // static function
   {
      #ifdef _DEBUG
         afxDump << "Full file name = " << status.m_szFullName << "\n";
      #endif
   }
