RPC_EE_INFO_PARAM structure (rpcasync.h)
The RPC_EE_INFO_PARAM structure is used to store extended error information.
Syntax
typedef struct tagRPC_EE_INFO_PARAM {
ExtendedErrorParamTypes ParameterType;
union {
LPSTR AnsiString;
LPWSTR UnicodeString;
long LVal;
short SVal;
ULONGLONG PVal;
BinaryParam BVal;
} u;
} RPC_EE_INFO_PARAM;
Members
ParameterType
Type of parameter being provided as extended error information. This value determines which union member(s) is used. Valid values are the following:
- eeptAnsiString to specify an ANSI string, indicating the value is provided in AnsiString.
- eeptUnicodeString to specify a Unicode string, indicating the value is provided in UnicodeString.
- eeptLongVal to specify a LONG value, indicating the value is provided in LVal.
- eeptShortVal to specify a SHORT value, indicating the values is provided in SVal.
- eeptPointerVal to specify a pointer value, indicating the values is provided in PVal.
- eeptBinary is used by the RPC Runtime and should not be used or specified by applications.
- eeptNone indicates the parameter contained either a Unicode or ANSI string, but was truncated due to lack of memory or network fragment length limitations.
u
u.AnsiString
ANSI string representing the extended error information.
u.UnicodeString
Unicode string representing the extended error information.
u.LVal
Long value representing the extended error information.
u.SVal
Short value representing the extended error information.
u.PVal
ULONGLONG value representing the extended error information.
u.BVal
Reserved.
Remarks
The RPC_EE_INFO_PARAM structure is used in conjunction with the RpcError* functions to investigate and create extended RPC error information.
