位元組物件 (Bytes Objects)

These functions raise TypeError when expecting a bytes parameter and called with a non-bytes parameter.

type PyBytesObject

This subtype of PyObject represents a Python bytes object.

PyTypeObject PyBytes_Type

為 穩定 ABI 的一部分.

This instance of PyTypeObject represents the Python bytes type; it is the same object as bytes in the Python layer.

int PyBytes_Check(PyObject *o)

Return true if the object o is a bytes object or an instance of a subtype of the bytes type. This function always succeeds.

int PyBytes_CheckExact(PyObject *o)

Return true if the object o is a bytes object, but not an instance of a subtype of the bytes type. This function always succeeds.

PyObject *PyBytes_FromString(const char *v)

回傳值：新的參照。 為 穩定 ABI 的一部分. Thread safety: Atomic.

Return a new bytes object with a copy of the string v as value on success, and NULL on failure. The parameter v must not be NULL; it will not be checked.

PyObject *PyBytes_FromStringAndSize(const char *v, Py_ssize_t len)

回傳值：新的參照。 為 穩定 ABI 的一部分. Thread safety: Atomic.

Return a new bytes object with a copy of the string v as value and length len on success, and NULL on failure. If v is NULL, the contents of the bytes object are uninitialized.

PyObject *PyBytes_FromFormat(const char *format, ...)

回傳值：新的參照。 為 穩定 ABI 的一部分. Thread safety: Atomic.

Take a C printf()-style format string and a variable number of arguments, calculate the size of the resulting Python bytes object and return a bytes object with the values formatted into it. The variable arguments must be C types and must correspond exactly to the format characters in the format string. The following format characters are allowed:

Format Characters	Type	Comment
%%	n/a	The literal % character.
%c	int	A single byte, represented as a C int.
%d	int	等價於 printf("%d"). [1]
%u	unsigned int	等價於 printf("%u"). [1]
%ld	long	等價於 printf("%ld"). [1]
%lu	unsigned long	等價於 printf("%lu"). [1]
%zd	Py_ssize_t	等價於 printf("%zd"). [1]
%zu	size_t	等價於 printf("%zu"). [1]
%i	int	等價於 printf("%i"). [1]
%x	int	等價於 printf("%x"). [1]
%s	const char*	A null-terminated C character array.
%p	const void*	The hex representation of a C pointer. Mostly equivalent to printf("%p") except that it is guaranteed to start with the literal 0x regardless of what the platform's printf yields.

An unrecognized format character causes all the rest of the format string to be copied as-is to the result object, and any extra arguments discarded.

[1] (1,2,3,4,5,6,7,8)

For integer specifiers (d, u, ld, lu, zd, zu, i, x): the 0-conversion flag has effect even when a precision is given.

PyObject *PyBytes_FromFormatV(const char *format, va_list vargs)

回傳值：新的參照。 為 穩定 ABI 的一部分. Thread safety: Atomic.

Identical to PyBytes_FromFormat() except that it takes exactly two arguments.

PyObject *PyBytes_FromObject(PyObject *o)

回傳值：新的參照。 為 穩定 ABI 的一部分. Thread safety: Safe for concurrent use on the same object.

Return the bytes representation of object o that implements the buffer protocol.

備註

If the object implements the buffer protocol, then the buffer must not be mutated while the bytes object is being created.

Py_ssize_t PyBytes_Size(PyObject *o)

為 穩定 ABI 的一部分. Thread safety: Atomic.

Return the length of the bytes in bytes object o.

Py_ssize_t PyBytes_GET_SIZE(PyObject
