CFile::GetStatus
This method retrieves status information related to a given CFile object instance or a given file path.
BOOL GetStatus(
CFileStatus& rStatus
) const;
static BOOL PASCAL GetStatus(
LPCTSTR lpszFileName,
CFileStatus& rStatus
);
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.
ULONGLONG 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, or it can contain a network path name.
Return Value
TRUE if the status information for the specified file is successfully obtained; otherwise, FALSE.
Remarks
The non-static version of GetStatus retrieves status information of the open file associated with the given CFile object. The static version of GetStatus obtains the file status from a given file path without actually opening the file. This is useful for testing the existence and access rights of a file.
The m_attribute member of the CFileStatus structure refers to the file attribute set. The CFile class provides the Attribute enumeration type so file attributes can be specified symbolically:
enum Attribute {
normal = 0x00,
readOnly = 0x01,
hidden = 0x02,
system = 0x04,
volume = 0x08,
directory = 0x10,
archive = 0x20
};
Example
CFile cfile;
cfile.Open(_T("SetLength_File.dat"), CFile::modeCreate |
CFile::modeReadWrite);
ULONGLONG dwNewLength = 10000;
cfile.SetLength(dwNewLength);
CFileStatus status;
if(cfile.GetStatus(status)) // virtual member function
{
TRACE(_T("File size = %u\n"), status.m_size);
}
TCHAR* pszFileName = _T("SetLength_File.dat");
if(CFile::GetStatus(pszFileName, status)) // static function
{
TRACE(_T("Full file name = %s\n"), status.m_szFullName);
}
