A dynamic string pointer, the one returned by STRPTR or other equivalent. |
Remarks
LEN will always make a copy of the string expression passed as parameter.
Use StrPtrLEN to avoid string copy in case of big strings like in the following example:
'---Define a 100Mb string
Dim MyString As String = String$(100000000, chr$(0))
MSGBOX 0, "Size: " & StrPtrLEN(STRPTR(MyString))
