NAME
im_makerw - make an IMAGE writeable
SYNOPSIS
#include <vips/vips.h> int im_makerw( image ) IMAGE *image;
DESCRIPTION

Its actions are just as those for im_incheck(3), except that descriptors which after im_incheck(3) end up as IM_MMAPIN descrip- tors, 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.
