These routines allow C code to work with serialized objects using the same
data format as the :mod:`marshal` module. There are functions to write data
into the serialization format, and additional functions that can be used to
read the data back. Files used to store marshalled data must be opened in
binary mode.

Numeric values are stored with the least significant byte first.

The module supports two versions of the data format: version 0 is the
historical version, version 1 shares interned strings in the file, and upon
unmarshalling. Version 2 uses a binary format for floating point numbers.
*Py_MARSHAL_VERSION* indicates the current file format (currently 2).

file will always result in a negative numeric value (where that's relevant),
but it's not clear that negative values won't be handled properly when there's
no error. What's the right way to tell? Should only non-negative values be
written using these routines?

reading. Unlike :cfunc:`PyMarshal_ReadObjectFromFile`, this function
assumes that no further objects will be read from the file, allowing it to
aggressively load file data into memory so that the de-serialization can
operate from data in memory rather than reading a byte at a time from the
file. Only use these variant if you are certain that you won't be reading
anything else from the file. On error, sets the appropriate exception
(:exc:`EOFError` or :exc:`TypeError`) and returns *NULL*.
