StrPtrLen

Description

Returns the length of a dynamic string giving its pointer.

Syntax

n = StrPtrLEN(DynamicStringPointer)

Returns

Number

Parameters

Name	Type	Optional	Meaning
DynamicStringPointer	Numeric	No	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))
