Signature de la méthode sendfile

def sendfile(self, file, offset=0, count=None) 

Description

help(socket.sendfile)

sendfile(file[, offset[, count]]) -> sent

        Send a file until EOF is reached by using high-performance
        os.sendfile() and return the total number of bytes which
        were sent.
        *file* must be a regular file object opened in binary mode.
        If os.sendfile() is not available (e.g. Windows) or file is
        not a regular file socket.send() will be used instead.
        *offset* tells from where to start reading the file.
        If specified, *count* is the total number of bytes to transmit
        as opposed to sending the file until EOF is reached.
        File position is updated on return or also in case of error in
        which case file.tell() can be used to figure out the number of
        bytes which were sent.
        The socket must be of SOCK_STREAM type.
        Non-blocking sockets are not supported.
