FreeMem

Releases a block of memory previously obtained from AllocMem.

Syntax: FreeMem MemPointer

MemPointer
required LongPtr. The address returned by a previous call to AllocMem.

The pointer is invalid after the call returns. Passing a pointer that did not come from AllocMem, or one that has already been freed, has undefined behaviour. A MemPointer of 0 does nothing.

Common Errors

Error When
94 (&H5E), Invalid use of Null MemPointer is Null

Example

This example allocates a buffer, uses it, and then releases it with FreeMem.

Dim buf As LongPtr = AllocMem(256)
' ... write and read buf ...
FreeMem buf    ' release the block; buf is invalid after this point
