I am assuming that Python delegates the f.seek call to the seek call in the MS C runtime library msvcrt.dll. Does anybody know a nice link to the Python source like was posted above for the BSD 'C' library?
Ok, I ran some more tests. C, seek : 0.812 seconds // test from original post Python, f.seek : 1.458 seconds. // test from original post C, time(&tm) : 0.671 seconds Python, time.time(): 0.513 seconds. Python, ctypes.msvcrt.time(ctypes.byref(tm)): 0.971 seconds. # factored the overhead to be outside the loop, so really this was func_ptr(ptr). Perhaps I am just comparing apples to oranges. I never tested the overhead of ctypes like this before. Most of my problem timings involve calls through ctypes. -- http://mail.python.org/mailman/listinfo/python-list
