"""
From https://docs.python.org/3.9/c-api/file.html
These APIs are a minimal emulation of the Python 2 C API for built-in file objects,
which used to rely on the buffered I/O (FILE*) support from the C standard library.
In Python 3, files and streams use the new io module, which defines several layers
over the low-level unbuffered I/O of the operating system. The functions described
below are convenience C wrappers over these new APIs, and meant mostly for internal
error reporting in the interpreter;
third-party code is advised to access the io APIs instead.

object PyFile_FromFd(int fd, const char *name, const char *mode, int buffering,
const char *encoding, const char *errors, const char *newline, int closefd)
# Return value: New reference.
# Create a Python file object from the file descriptor of an already
# opened file fd. The arguments name, encoding, errors and newline can be
# NULL to use the defaults; buffering can be -1 to use the default. name
# is ignored and kept for backward compatibility. Return NULL on failure.
# For a more comprehensive description of the arguments, please refer to
# the io.open() function documentation.
# Warning: Since Python streams have their own buffering layer, mixing
# them with OS-level file descriptors can produce various issues (such as
# unexpected ordering of data).
# Changed in version 3.2: Ignore name attribute.
object PyFile_GetLine(object p, int n)
# Return value: New reference.
# Equivalent to p.readline([n]), this function reads one line from the
# object p. p may be a file object or any object with a readline()
# method. If n is 0, exactly one line is read, regardless of the length of
# the line. If n is greater than 0, no more than n bytes will be read from
# the file; a partial line can be returned. In both cases, an empty string
# is returned if the end of the file is reached immediately. If n is less
# than 0, however, one line is read regardless of length, but EOFError is
# raised if the end of the file is reached immediately.
int PyFile_WriteObject(object obj, object p, int flags) except? -1
# Write object obj to file object p. The only supported flag for flags
# is Py_PRINT_RAW; if given, the str() of the object is written instead of
# the repr(). Return 0 on success or -1 on failure; the appropriate
# exception will be set.
int PyFile_WriteString(const char *s, object p) except? -1
# Write string s to file object p. Return 0 on success or -1 on failure;
# the appropriate exception will be set.
