Adding libraw_datastream_read to C-API To solve the issue of reading EXIF copyright data using the C-API, I added a simple function in libraw_c_api.c: DllDef int libraw_datastream_read(void *ifp, void *ptr, size_t size, size_t nmemb) { if (!ifp) return -1; return ((LibRaw_abstract_datastream *)ifp)->read(ptr, size, nmemb); } Then from my application I can call that function from the exifparser callback installed using libraw_set_exifparser_handler. Simple and easy. Of course other similar functions may be added to call various LibRaw_abstract_datastream methods . reply
