I need to import a large mixed-format binary file. This is best done using memmapfile. However, the data has also been written in big-endian.
Short of a time consuming loop through the 50,000 lines of the structure, and all of the associated structure fields, is there any way to reverse the endian-ness of everything that comes out of the Data field from memmapfile?
Alternatively, I could do some gruesome struct2cell juggling.Yuck.
Bottom line: is there a way to reverse the endian-ness of memmapfile? If not, that should be added.
