I am currently studying a project in which a application that use C standard file I/O functions will be ported onto Nucleus. The toolchain might be the GNU one.
I am looking for information on how to port the glibC. I quickly looked at lib2.2.4 sources and saw the interesting sysdeps/standalone directory but it would provides console i/o only. I think the all libC is based on low levels functions that may be customized for each target but I cannot see easily this border..
