SysAllocStringLen function

Allocates a new string, copies the specified number of characters from the passed string, and appends a null-terminating character.

Syntax

BSTR SysAllocStringLen(
  _In_ const OLECHAR *strIn,
  _In_       UINT    ui
);

Parameters

strIn [in]

The input string.

ui [in]

The number of characters to copy. A null character is placed afterwards, allocating a total of ui plus one characters.

Return value

A copy of the string, or NULL if there is insufficient memory to complete the operation.

Remarks

The string can contain embedded null characters and does not need to end with a NULL. Free the returned string later with SysFreeString. If strIn is not NULL, then the memory allocated to strIn must be at least ui characters long.
