Initializes a VARIANT structure with the contents of a buffer.

Syntax

PSSTDAPI InitVariantFromBuffer( [in] const void *pv, [in] UINT cb, [out] VARIANT *pvar ); 

Parameters

[in] pv

Type: const VOID*

Pointer to the source buffer.

[in] cb

Type: UINT

The length of the buffer, in bytes.

[out] pvar

Type: VARIANT*

When this function returns, contains the initialized VARIANT structure.

Return value

Type: HRESULT

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

Creates a VT_ARRAY | VT_UI1 variant..

Examples

The following example, to be included as part of a larger program, demonstrates how to use InitVariantFromBuffer.

// void *pv; // UINT cb; // Assume variable pv and cb are initialized and valid. pv points to a // buffer and cb contains the size of the buffer in bytes. VARIANT var; HRESULT hr = InitVariantFromBuffer(pv, cb, & var); if (SUCCEEDED(hr)) { // var now is valid and has type VT_ARRAY | VT_UI1. VariantClear(&var); }
