NAME

       im_makerw - make an IMAGE writeable

SYNOPSIS

       #include <vips/vips.h>

       int im_makerw( image )
       IMAGE *image;

DESCRIPTION

       im_makerw(3)  attempts  to  make image writeable, ready for an in-place
       operation.  Its actions are just as  those  for  im_incheck(3),  except
       that   descriptors  which  after  im_incheck(3)  end  up  as  IM_MMAPIN
       descriptors, magically become IM_MMAPINRW descriptors.

       Extreme caution is urged! You can permanently damage valuable data with
       this call.

RETURN VALUE

       The function returns 0 on success and -1 on error.
