Hi Ed,Here is a small example that I hope will give you an idea how to use H5Tget_order to get information you need:
#include "hdf5.h"
int main() {
H5T_order_t order;
hid_t type;
order = H5Tget_order(H5T_NATIVE_INT);
printf("order is %d \n", order);
type = H5Tcopy(H5T_STD_I32LE);
order = H5Tget_order(type);
printf("order is %d \n", order);
H5Tclose(type);
}
If you run it on AIX system (big-endian) you will get
order is 1
order is 0
where 1 stands for big-endian, and 0 stands for little-endian
H5Tget_native_type is used to construct memory type from the file type
avoiding building the memory type from scratch (finding class, size,
precision, etc). It is a short cut. In general user still has to know the
size and the type of the buffer to read data in.

Howdy all! I have a HDF5 question. I see that the function H5Tget_order can tell me if a type is big or little endian. But is there a way to tell if a type is native endian for that machine? What is H5Tget_native_type all about? Is this it's purpose? To tell me if a type is native? They I could use H5Tget_order to find if something is big or little endian, and then somehow get_native_type to tell whether this is the native endianness for the machine? Is that it? Thanks!
