CPtrkeyword

Converts a pointer expression to a specified data type pointer

Converting Data Typeskeyworddocumented

Syntax

CPtr( PointerDataType, expression )

Description


Converts expression to PointerDataType.

PointerDataType must be a Pointer type (e.g. a DataType Ptr or an Any Ptr), or a Type (Alias) to one.
expression may have a different pointer type or be an Integer.

Note: Currently, FB does not actually enforce that PointerDataType must be a pointer. This will likely change in future versions though. Currently, it may display a warning if you try to convert to a non-pointer (for any conversion type if you compile with the -w pedantic compiler switch).

Example


Dim intval As Integer

Dim intptr As Integer Ptr

intval = &h0080

intptr = @intval

'' will print -128 and 128, as the first expression will be "seen" as an signed byte

Print *CPtr( Byte Ptr, intptr ), *intptr
