tag_name

Apply this attribute to a method in a request handler to expose it as a replacement method associated with a tag name.

[ tag_name(
      name,
   parse_func
) ]

Parameters

• name
  A string specifying the tag name for the replacement handler that will invoke this method.

• parse_func (optional)
  Specifies the name of the function used to parse arguments passed to the method.

Remarks

This attribute is used to classify a method as a replacement method. A method may have multiple tag_name attributes.

If parse_func is specified, the parse function should have the following signature:

HTTP_CODE parse_func(IAtlMemMgr* pMemoryManager, LPCSTR szArg, Type** ppArg);

The replacement method should have a corresponding signature:

HTTP_CODE methodFunc(Type* pArg);

If parse_func is omitted, the method should have a signature in one of the following forms:

HTTP_CODE MethodName();
HTTP_CODE MethodName(Type* pArg);

Where Type can be one of the types listed:

Use of this attribute corresponds to the REPLACEMENT_METHOD_ENTRY macro when the method does not have a parameter, and it corresponds to REPLACEMENT_METHOD_ENTRY_EX when the method does have a parameter.
