  • Article

The RtlCopyString routine copies a source string to a destination string.

  [in, optional] const STRING *SourceString
);

Parameters

[out] DestinationString

A pointer to the destination string buffer.

[in, optional] SourceString

Remarks

The DestinationString Length is set to zero if no source string is supplied. The MaximumLength and Buffer members of the DestinationString are not modified by this routine.

The DestinationString and SourceString buffers must be resident if the caller is running at IRQL >= DISPATCH_LEVEL.
