The macro puts a pointer to a C structure 13 into a static variable, :c:data:`PyDateTimeAPI`, that is used by the following 14 macros. 15 16 Type-check macros: 17 18 19 .. c:function:: int PyDate_Check(PyObject *ob) 20 21 Return true if *ob* is of type :c:data:`PyDateTime_DateType` or a subtype of 22 :c:data:`PyDateTime_DateType`. *ob* must not be *NULL*. 23 24 .. versionadded:: 2.4 25 26 27 .. c:function:: int PyDate_CheckExact(PyObject *ob) 28 29 Return true if *ob* is of type :c:data:`PyDateTime_DateType`. *ob* must not be 30 *NULL*. 31 32 .. versionadded:: 2.4 33 34 35 .. c:function:: int PyDateTime_Check(PyObject *ob) 36 37 Return true if *ob* is of type :c:data:`PyDateTime_DateTimeType` or a subtype of 38 :c:data:`PyDateTime_DateTimeType`. *ob* must not be *NULL*. 39 40 .. versionadded:: 2.4 41 42 43 .. c:function:: int PyDateTime_CheckExact(PyObject *ob) 44 45 Return true if *ob* is of type :c:data:`PyDateTime_DateTimeType`. *ob* must not 46 be *NULL*. 47 48 .. versionadded:: 2.4 49 50 51 .. c:function:: int PyTime_Check(PyObject *ob) 52 53 Return true if *ob* is of type :c:data:`PyDateTime_TimeType` or a subtype of 54 :c:data:`PyDateTime_TimeType`. *ob* must not be *NULL*. 55 56 .. versionadded:: 2.4 57 58 59 .. c:function:: int PyTime_CheckExact(PyObject *ob) 60 61 Return true if *ob* is of type :c:data:`PyDateTime_TimeType`. *ob* must not be 62 *NULL*. 63 64 .. versionadded:: 2.4 65 66 67 .. c:function:: int PyDelta_Check(PyObject *ob) 68 69 Return true if *ob* is of type :c:data:`PyDateTime_DeltaType` or a subtype of 70 :c:data:`PyDateTime_DeltaType`. *ob* must not be *NULL*. 71 72 .. versionadded:: 2.4 73 74 75 .. c:function:: int PyDelta_CheckExact(PyObject *ob) 76 77 Return true if *ob* is of type :c:data:`PyDateTime_DeltaType`. *ob* must not be 78 *NULL*. 79 80 .. versionadded:: 2.4 81 82 83 .. c:function:: int PyTZInfo_Check(PyObject *ob) 84 85 Return true if *ob* is of type :c:data:`PyDateTime_TZInfoType` or a subtype of 86 :c:data:`PyDateTime_TZInfoType`. *ob* must not be *NULL*. 87 88 .. versionadded:: 2.4 89 90 91 .. c:function:: int PyTZInfo_CheckExact(PyObject *ob) 92 93 Return true if *ob* is of type :c:data:`PyDateTime_TZInfoType`. *ob* must not be 94 *NULL*. 95 96 .. versionadded:: 2.4 97 98 Macros to create objects: 99 100 101 .. c:function:: PyObject* PyDate_FromDate(int year, int month, int day) 102 103 Return a ``datetime.date`` object with the specified year, month and day. 104 105 .. versionadded:: 2.4 106 107 108 .. c:function:: PyObject* PyDateTime_FromDateAndTime(int year, int month, int day, int hour, int minute, int second, int usecond) 109 110 Return a ``datetime.datetime`` object with the specified year, month, day, hour, 111 minute, second and microsecond. 112 113 .. versionadded:: 2.4 114 115 116 .. c:function:: PyObject* PyTime_FromTime(int hour, int minute, int second, int usecond) 117 118 Return a ``datetime.time`` object with the specified hour, minute, second and 119 microsecond. 120 121 .. versionadded:: 2.4 122 123 124 .. c:function:: PyObject* PyDelta_FromDSU(int days, int seconds, int useconds) 125 126 Return a ``datetime.timedelta`` object representing the given number of days, 127 seconds and microseconds.
