NAME
     minherit - control the inheritance of pages



SYNOPSIS
     #include <sys/types.h>
     #include <sys/mman.h>
     #include <vm/vm_inherit.h>

     int
     minherit(void *addr, size_t len, int inherit);

DESCRIPTION
     The minherit() system call changes the specified pages to have the inher-
     itance characteristic inherit, which can be set to VM_INHERIT_NONE,
     VM_INHERIT_COPY, or VM_INHERIT_SHARE. Not all implementations will guar-
     antee that the inheritance characteristic can be set on a page basis; the
     granularity of changes may be as large as an entire region.
