CGopherLocator Class

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at CGopherLocator Class.

Gets a gopher "locator" from a gopher server, determines the locator's type, and makes the locator available to CGopherFileFind.

Note

The classes CGopherConnection, CGopherFile, CGopherFileFind, CGopherLocator and their members have been deprecated because they do not work on the Windows XP platform, but they will continue to work on earlier platforms.

Syntax

class CGopherLocator : public CObject  

Members

Public Constructors

Name Description
CGopherLocator::CGopherLocator Constructs a CGopherLocator object.

Public Methods

Name Description
CGopherLocator::GetLocatorType Parses a gopher locator and determines its attributes.

Public Operators

Name Description
CGopherLocator::operator LPCTSTR Directly accesses characters stored in a CGopherLocator object as a C-style string.

Remarks

An application must get a gopher server's locator before it can retrieve information from that server. Once it has the locator, it must treat the locator as an opaque token.

Each gopher locator has attributes that determine the type of file or server found. See GetLocatorType for a list of types of gopher locators.

An application normally uses the locator for calls to CGopherFileFind::FindFile to retrieve a specific piece of information.

To learn more about how CGopherLocator works with the other MFC Internet classes, see the article Internet Programming with WinInet.

CGopherLocator::CGopherLocator

This member function is called to create a CGopherLocator object.

CGopherLocator(const CGopherLocator& ref);

Parameters

ref
A reference to a constant CGopherLocator object.

Remarks

You never create a CGopherLocator object directly. Instead, call CGopherConnection::CreateLocator to create and return a pointer to the CGopherLocator object.

CGopherLocator::GetLocatorType

Call this member function to get the locator type.

BOOL GetLocatorType(DWORD& dwRef) const;  

Parameters

dwRef
A reference to a DWORD that will receive the locator type. See Remarks for a table of locator types.

Return Value

Nonzero if successful; otherwise 0. If the call fails, the Win32 function GetLastError may be called to determine the cause of the error.

Remarks

The possible types are as follows:

GOPHER_TYPE_TEXT_FILE An ASCII text file.
GOPHER_TYPE_DIRECTORY A directory of additional Gopher items.
