StorPortSecureCopyMemory securely copies bytes between buffers.
Dest [out]Pointer to the destination buffer to copy to.
DestSizeInBytes [in]Size of the buffer that Dest points to, in bytes.
Src [in]Pointer to the source buffer to copy from.
Count [in]Number of bytes to copy from Src to Dest.
This function returns one of the following status codes.
| Return code | Description |
|---|---|
| STOR_STATUS_SUCCESS | The specified number of bytes were copied. |
| STOR_STATUS_INVALID_PARAMETER | A parameter is invalid; for example, Dest is a null pointer. |
| STOR_STATUS_BUFFER_TOO_SMALL | The destination buffer size is smaller than number of bytes to copy. |
A miniport calls StorPortSecureCopyMemory to securely copy bytes from a virtual source buffer to a virtual destination buffer. To avoid any potential security vulnerabilities, miniports should call this function instead of StorPortCopyMemory.
