# 7.2.3 Long Integer Objects
############################################################################
# PyLongObject
#
# This subtype of PyObject represents a Python long integer object.
# PyTypeObject PyLong_Type
#
# This instance of PyTypeObject represents the Python long integer
# type. This is the same object as long and types.LongType.
bint PyLong_Check(object p)
# Return true if its argument is a PyLongObject or a subtype of PyLongObject.
bint PyLong_CheckExact(object p)
# Return true if its argument is a PyLongObject, but not a subtype of PyLongObject.
object PyLong_FromLong(long v)
# Return value: New reference.
# Return a new PyLongObject object from v, or NULL on failure.
object PyLong_FromUnsignedLong(unsigned long v)
# Return value: New reference.
# Return a new PyLongObject object from a C unsigned long, or NULL on failure.
object PyLong_FromLongLong(PY_LONG_LONG v)
# Return value: New reference.
# Return a new PyLongObject object from a C long long, or NULL on failure.
object PyLong_FromUnsignedLongLong(uPY_LONG_LONG v)
# Return value: New reference.
# Return a new PyLongObject object from a C unsigned long long, or NULL on failure.
object PyLong_FromDouble(double v)
# Return value: New reference.
# Return a new PyLongObject object from the integer part of v, or NULL on failure.
object PyLong_FromString(char *str, char **pend, int base)
# Return value: New reference.
# Return a new PyLongObject based on the string value in str,
# which is interpreted according to the radix in base. If pend is
# non-NULL, *pend will point to the first character in str which
# follows the representation of the number. If base is 0, the
# radix will be determined based on the leading characters of str:
# if str starts with '0x' or '0X', radix 16 will be used; if str
# starts with '0', radix 8 will be used; otherwise radix 10 will
# be used. If base is not 0, it must be between 2 and 36,
# inclusive. Leading spaces are ignored. If there are no digits,
# ValueError will be raised.
object PyLong_FromUnicode(Py_UNICODE *u, Py_ssize_t length, int base)
# Return value: New reference.
# Convert a sequence of Unicode digits to a Python long integer
# value. The first parameter, u, points to the first character of
# the Unicode string, length gives the number of characters, and
# base is the radix for the conversion. The radix must be in the
# range [2, 36]; if it is out of range, ValueError will be
# raised.
object PyLong_FromVoidPtr(void *p)
# Return value: New reference.
# Create a Python integer or long integer from the pointer p. The
# pointer value can be retrieved from the resulting value using
# PyLong_AsVoidPtr(). If the integer is larger than LONG_MAX, a
# positive long integer is returned.
long PyLong_AsLong(object pylong) except? -1
# Return a C long representation of the contents of pylong. If
# pylong is greater than LONG_MAX, an OverflowError is raised.
unsigned long PyLong_AsUnsignedLong(object pylong) except? -1
# Return a C unsigned long representation of the contents of
# pylong. If pylong is greater than ULONG_MAX, an OverflowError is
# raised.
PY_LONG_LONG PyLong_AsLongLong(object pylong) except? -1
# Return a C long long from a Python long integer. If pylong
# cannot be represented as a long long, an OverflowError will be
# raised.
uPY_LONG_LONG PyLong_AsUnsignedLongLong(object pylong) except? -1
#unsigned PY_LONG_LONG PyLong_AsUnsignedLongLong(object pylong)
# Return a C unsigned long long from a Python long integer. If
# pylong cannot be represented as an unsigned long long, an
# OverflowError will be raised if the value is positive, or a
# TypeError will be raised if the value is negative.
unsigned long PyLong_AsUnsignedLongMask(object io) except? -1
# Return a C unsigned long from a Python long integer, without
# checking for overflow.
uPY_LONG_LONG PyLong_AsUnsignedLongLongMask(object io) except? -1
#unsigned PY_LONG_LONG PyLong_AsUnsignedLongLongMask(object io)
# Return a C unsigned long long from a Python long integer,
# without checking for overflow.
double PyLong_AsDouble(object pylong) except? -1.0
# Return a C double representation of the contents of pylong. If
# pylong cannot be approximately represented as a double, an
# OverflowError exception is raised and -1.0 will be returned.
void* PyLong_AsVoidPtr(object pylong) except? NULL
# Convert a Python integer or long integer pylong to a C void
# pointer. If pylong cannot be converted, an OverflowError will be
# raised. This is only assured to produce a usable void pointer
# for values created with PyLong_FromVoidPtr(). For values outside
# 0..LONG_MAX, both signed and unsigned integers are acccepted.
