NdrConformantStringUnmarshall function (rpcndr.h)

  • Article

The NdrConformantStringUnmarshall function unmarshals the conformant string from the network buffer to memory.

Syntax

unsigned char * NdrConformantStringUnmarshall(
  [in, out] PMIDL_STUB_MESSAGE pStubMsg,
  [out]     unsigned char      **ppMemory,
  [in]      PFORMAT_STRING     pFormat,
  [in]      unsigned char      fMustAlloc
);

Parameters

[in, out] pStubMsg

Pointer to a MIDL_STUB_MESSAGE structure that maintains the current status of the RPC stub. This structure is for internal use only and should not be modified.

[out] ppMemory

Address to a pointer to the unmarshalled conformant string. If set to null, or if the fMustAlloc is set to TRUE, the stub will allocate the memory.

[in] pFormat

Pointer to the format string description.

[in] fMustAlloc

Flag that specifies whether the stub must allocate the memory into which the conformant string is to be marshaled. Specify TRUE if RPC must allocate ppMemory.

Return value

Returns null upon success. If an error occurs, the function throws one of the following exception codes.

Error Description
RPC_BAD_STUB_DATA or RPC_X_INVALID_BOUND The network is incorrect.
RPC_S_OUT_OF_MEMORY Out of memory.
