Hi Andrea,

H5Pget_file_image wants to allocate the memory for the file image itself, either with malloc or with some function provided by the application using H5Pset_file_image_callbacks. I find this design needlessly complex (perhaps due to my ignorance). Why couldn’t H5Pget_file_image let the application do the allocation just like, say,H5Fget_file_image? H5Fget_file_image has to be called twice. First, to retrieve the size of the buffer needed, then to retrieve the file itself. H5Pget_file_image is called only once. You are correct, the design is complex. I guess the thinking was to be helpful ;-) Elena Thanks in advance, Andrea -- Andrea Bedini @andreabedini, http://www.andreabedini.com<http://www.andreabedini.com/> See the impact of my research at https://impactstory.org/AndreaBedini use https://keybase.io/andreabedini to send me encrypted messages Key fingerprint = 17D5 FB49 FA18 A068 CF53 C5C2 9503 64C1 B2D5 9591 _______________________________________________ Hdf-forum is for HDF software users discussion.
