# Integer Objects
############################################################################
# PyTypeObject PyInt_Type
# This instance of PyTypeObject represents the Python plain
# integer type. This is the same object as int and types.IntType.
bint PyInt_Check(object o)
# Return true if o is of type PyInt_Type or a subtype of
# PyInt_Type.
bint PyInt_CheckExact(object o)
# Return true if o is of type PyInt_Type, but not a subtype of
# PyInt_Type.
object PyInt_FromString(char *str, char **pend, int base)
# Return value: New reference.
# Return a new PyIntObject or 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. If the string
# represents a number too large to be contained within the
# machine's long int type and overflow warnings are being
# suppressed, a PyLongObject will be returned. If overflow
# warnings are not being suppressed, NULL will be returned in this
# case.
object PyInt_FromLong(long ival)
# Return value: New reference.
# Create a new integer object with a value of ival.
# The current implementation keeps an array of integer objects for
# all integers between -5 and 256, when you create an int in that
# range you actually just get back a reference to the existing
# object. So it should be possible to change the value of 1. I
# suspect the behaviour of Python in this case is undefined. :-)
object PyInt_FromSsize_t(Py_ssize_t ival)
# Return value: New reference.
# Create a new integer object with a value of ival. If the value
# is larger than LONG_MAX or smaller than LONG_MIN, a long integer
# object is returned.
object PyInt_FromSize_t(size_t ival)
# Return value: New reference.
# Create a new integer object with a value of ival. If the value
# exceeds LONG_MAX, a long integer object is returned.
long PyInt_AsLong(object io) except? -1
# Will first attempt to cast the object to a PyIntObject, if it is
# not already one, and then return its value. If there is an
# error, -1 is returned, and the caller should check
# PyErr_Occurred() to find out whether there was an error, or
# whether the value just happened to be -1.
long PyInt_AS_LONG(object io)
# Return the value of the object io. No error checking is performed.
unsigned long PyInt_AsUnsignedLongMask(object io) except? -1
# Will first attempt to cast the object to a PyIntObject or
# PyLongObject, if it is not already one, and then return its
# value as unsigned long. This function does not check for
# overflow.
PY_LONG_LONG PyInt_AsUnsignedLongLongMask(object io) except? -1
# Will first attempt to cast the object to a PyIntObject or
# PyLongObject, if it is not already one, and then return its
# value as unsigned long long, without checking for overflow.
Py_ssize_t PyInt_AsSsize_t(object io) except? -1
# Will first attempt to cast the object to a PyIntObject or
# PyLongObject, if it is not already one, and then return its
# value as Py_ssize_t.
long PyInt_GetMax()
# Return the system's idea of the largest integer it can handle
# (LONG_MAX, as defined in the system header files).
int PyInt_ClearFreeList()
# Clear the integer free list. Return the number of items that could not be freed.
# New in version 2.6.
