.SH "DESCRIPTION"
.PP
Initialize a new offset\-manager\&. The offset and area size available for the manager are given as
\fIpage_offset\fR
and
\fIsize\fR\&. Both are interpreted as page\-numbers, not bytes\&.
.PP
Adding/removing nodes from the manager is locked internally and protected against concurrent access\&. However, node allocation and destruction is left for the caller\&. While calling into the vma\-manager, a given node must always be guaranteed to be referenced\&.
