ok = PyArg_ParseTuple(args, "(ii)s#", &i, &j, &s, &size); /* A pair of ints and a string, whose size is also returned */ /* Possible Python call: f((1, 2), 'three') */ { char *file; char *mode = "r"; int bufsize = 0; ok = PyArg_ParseTuple(args, "s|si"...
当定义一个函数调用PyArg_ParseTuple函数时传递true,如下所示: 在上面的例子中,我们在PyArg_ParseTuple函数的调用中传递了true参数。这样一旦参数解析失败,就会调用PyErr_SetString函数来打印错误信息,并继续执行函数体内的代码。这样可以提高函数的鲁棒性,使其在参数解析失败时不会直接崩溃。 第二篇示例: Python是一种...
int ok; int i, j; long k, l; char *s; int size; ok = PyArg_ParseTuple(args, ""); /* No arguments */ /* Python call: f() */ ok = PyArg_ParseTuple(args, "s", &s); /* A string */ /* Possible Python call: f('whoops!') */ ok = PyArg_ParseTuple(args, "lls...

int PyArg_ParseTuple(PyObject *arg, char *format, ...); 1. Theargargument must be a tuple object containing an argument list passed from Python to a C function. Theformatargument must be a format string, whose syntax is explained below. The remaining arguments must be addresses of variab...
We use the “y*” format code in PyArg_ParseTuple to parse the bytearray. This code expects a bytes-like object (including bytes, bytearray, or any object that supports the buffer protocol) and fills a Py_buffer structure. The Py_buffer structure provides access to the underlying memory ...
PyArg_ParseTuple()将使用PyMem_NEW()分配一个所需大小的缓冲区,将已编码的数据复制到这个缓冲区中,并调整*buffer以引用新分配的存储。调用方负责调用PyMem_Free()以在使用后释放分配的缓冲区。 "es#" (string,Unicode object or character buffer compatible object) [const char *encoding,char **buffer, int...
