RUMPUSER(3)             NetBSD Library Functions Manual            RUMPUSER(3)


NAME

     rumpuser -- rump user namespace helper routines


LIBRARY

     rump User Library (librumpuser, -lrumpuser)


SYNOPSIS

     #include <rump/rumpuser.h>


DESCRIPTION

     rumpuser is a user namespace helper library for runnable userspace meta
     programs.  From rump emulation code compiled with -D_KERNEL is it not
     possible to directly call routines such as system calls for reading and
     writing files or devices.  This is where rumpuser comes into play by pro-
     viding a bridge between the two namespaces.  Another example of its ser-
     vices is a way to call pthread routines, used for emulating kernel
     threads and synchronization mechanisms in rump.
