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.
