[MINC-users] minc2 api question - miget_volume_dimensions

[EJ Nikelski]

Hi Claude (and list),

  Yes. That compiles and runs without a seg fault (always a bonus).
Although I'm a little confused by the fact that when I do a
"printf("Size of:%d.\n", sizeof(midimhandle_t));", I get a size of 4
(the pointer, I suppose).  Should malloc not be allocating enough
space for the entire struct?

  Anyways, nuff work for one day -- I'm off to feed the beagle.

Thanks,

-Jim
