:relfileprefix: ../../../
:mrdocs:

Release the managed memory and reset this proctor to manage a different block.

== Synopsis

Declared in `<bslma_deallocatebytesproctor.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
void
reset(
    xref:BloombergLP/bslma/DeallocateBytesProctor.adoc[PtrType] p,
    std::size_t nbytes,
    std::size_t alignment = k_MAX_ALIGNMENT);
----

== Description

Release the managed memory and reset this proctor to manage the specified `nbytes` bytes at the specified `p` address. Optionally specify the `alignment` used to allocate `p`. If `p` is null, then the proctor is disengaged (manages no memory). The behavior is undefined unless `p` is null or was allocated with a size of `nbytes` and alignment of `alignment` from the same allocator used to construct this proctor. Note that the previously managed block is not deallocated.

== Parameters

| *p*
| address of the memory block to manage, or null
| *nbytes*

| *alignment*
