.SH "DESCRIPTION"
Resizes the memory buffer referenced by \fIp\fP to \fIlen\fP bytes. The returned
buffer may be relocated. On successful expansion, any newly allocated
portion of the buffer is zero-initialized.

If \fIp\fP is NULL, this function behaves like \fBlibnvme_alloc\fP.
.SH "RETURN"
Pointer to the resized memory buffer on success, or NULL on failure.
On failure, the original buffer referenced by \fIp\fP remains valid and
unchanged.
