The arguments are the same as for python's built-in C{file} (aka C{open}). A file-like object is returned, which closely mimics the behavior of a normal python file object. The mode indicates how the file is to be opened: C{'r'} for reading, C{'w'} for writing (truncating an existing file), C{'a'} for appending, C{'r+'} for reading/writing, C{'w+'} for reading/writing (truncating an existing file), C{'a+'} for reading/appending. The python C{'b'} flag is ignored, since SSH treats all files as binary. The C{'U'} flag is supported in a compatible way. Since 1.5.2, an C{'x'} flag indicates that the operation should only succeed if the file was created and did not previously exist. This has no direct mapping to python's file flags, but is commonly known as the C{O_EXCL} flag in posix. The file will be buffered in standard python style by default, but can be altered with the C{bufsize} parameter. C{0} turns off buffering, C{1} uses line buffering, and any number greater than 1 (C{>1}) uses that specific buffer size. @param filename: name of the file to open @type filename: str @param mode: mode (python-style) to open in @type mode: str @param bufsize: desired buffering (-1 = default buffer size) @type bufsize: int @return: a file object representing the open file @rtype: SFTPFile @raise IOError: if the file could not be opened. s open(%r, %r)iRXt+twtaR)sExpected handlesopen(%r, %r) -> %s(RBR$RCtSFTP_FLAG_READtSFTP_FLAG_WRITEtSFTP_FLAG_CREATEtSFTP_FLAG_TRUNCtSFTP_FLAG_APPENDtSFTP_FLAG_EXCLRRDtCMD_OPENRFRGRHRR( R&R=tmodetbufsizetimodet attrblockR.R6RQ((sSC:\Documents and Settings\red08xgu\Desktop\python_webupdate\paramiko\sftp_client.pytopenÄs(#'      #cCs7|i|ƒ}|itd|ƒ|it|ƒdS(s- Remove the file at the given path.

The return value is an object whose attributes correspond to the attributes of python's C{stat} structure as returned by C{os.stat}, except that it contains fewer fields. An SFTP server may return as much or as little info as it wants, so the results may vary from server to server. Unlike a python C{stat} object, the result may not be accessed as a tuple. This is mostly due to the author's slack factor.
