Creates a parameter definition with the specified signature for the method referenced by the specified token, and gets a token for that parameter definition.

Syntax

HRESULT DefineParam (
    [in]  mdMethodDef md,
    [in]  ULONG       ulParamSeq,
    [in]  LPCWSTR     szName,
    [in]  DWORD       dwParamFlags,
    [in]  DWORD       dwCPlusTypeFlag,
    [in]  void const  *pValue,
    [in]  ULONG       cchValue,
    [out] mdParamDef  *ppd
);

Parameters

md [in] The token for the method whose parameter is being defined.

ulParamSeq [in] The parameter sequence number.

szName [in] The name of the parameter in Unicode.

dwParamFlags [in] Flags for the parameter. This is a bitmask of CorParamAttr values.

dwCPlusTypeFlag [in] ELEMENT_TYPE_* for the constant value.

pValue [in] The constant value for the parameter.

cchValue [in] The size, in Unicode characters, of pValue.

ppd [out] The mdParamDef token assigned.

Remarks

The sequence values in ulParamSeq begin with 1 for parameters. A return value has a sequence number of 0.
