Massive automated renaming of all Py_/PyObject/etc. prefixes to Ty_/TyObject/etc. This includes: - All public API types (TyObject, TyTypeObject, etc.) - All public API functions (Ty_Initialize, Ty_BuildValue, etc.) - All internal API (_Ty_ prefixes) - Reference counting macros (Ty_INCREF, Ty_DECREF, etc.) - Type flags (Ty_TPFLAGS_*) - Debug flags (Ty_DEBUG, Ty_TRACE_REFS, etc.) - All object type APIs (TyList_, TyDict_, TyUnicode_, etc.) This changes over 60,000 occurrences across 1000+ files.

/* TyLong_AsNativeBytes: Copy the integer value to a native variable.
|
|
buffer points to the first byte of the variable.
|
|
n_bytes is the number of bytes available in the buffer. Pass 0 to request
|
|
the required size for the value.
|
|
flags is a bitfield of the following flags:
|
|
* 1 - little endian
|
|
* 2 - native endian
|
|
* 4 - unsigned destination (e.g. don't reject copying 255 into one byte)
|
|
* 8 - raise an exception for negative inputs
|
|
* 16 - call __index__ on non-int types
|
|
If flags is -1 (all bits set), native endian is used, value truncation
|
|
behaves most like C (allows negative inputs and allow MSB set), and non-int
|
|
objects will raise a TypeError.
|
|
Big endian mode will write the most significant byte into the address
|
|
directly referenced by buffer; little endian will write the least significant
|
|
byte into that address.
|
|
|
|
If an exception is raised, returns a negative value.
|
|
Otherwise, returns the number of bytes that are required to store the value.
|
|
To check that the full value is represented, ensure that the return value is
|
|
equal or less than n_bytes.
|
|
All n_bytes are guaranteed to be written (unless an exception occurs), and
|
|
so ignoring a positive return value is the equivalent of a downcast in C.
|
|
In cases where the full value could not be represented, the returned value
|
|
may be larger than necessary - this function is not an accurate way to
|
|
calculate the bit length of an integer object.
