Pokesub

Assigns a value to a location in memory.

Syntax

Declare Sub Poke ( ByVal address As Any Ptr, ByRef value As UByte )

Declare Sub Poke ( datatype, ByVal address As Any Ptr, ByRef value As datatype )

Parameters

Name		Description
`datatype`		The type of data at the specified address. If omitted, `UByte` is assumed.
`address`		The location in memory to assign to.
`value`		The value to assign.

Description

Poke assigns a value to a location in memory. It is equivalent to

*cast(ubyte ptr, address) = value

*cast(datatype ptr, address) = value

When datatype is a user-defined type, Poke assigns value using the type's Operator Let.

Note: When using Poke, the -exx compiler option does not add code for null-pointer checking (no nullity test on the value of address).

Remarks

Usage



Poke [ datatype, ] address, value

Differences from QB

Only the byte form were supported in QB.
DEF SEG isn't needed anymore because the address space is 32-bit flat in FreeBASIC.

Example

Dim i As Integer, p As Integer Ptr

p = @i



Poke Integer, p, 420

Print Peek(Integer, p)

Will produce the output:
