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.

Note  This function does not convert a char * string into a Unicode BSTR.
