libssh2_sftp_read - read data from an SFTP handle

handle is the SFTP File Handle as returned by libssh2_sftp_open_ex(3)buffer is a pointer to a pre-allocated buffer of at least

       buffer_maxlen bytes to read data into.

       Reads  a  block  of  data  from  an  LIBSSH2_SFTP_HANDLE. This method is modelled after the POSIX read(2)
       function and uses the same calling semantics.  libssh2_sftp_read(3) will  attempt  to  read  as  much  as
       possible  however  it  may not fill all of buffer if the file pointer reaches the end or if further reads
       would cause the socket to block.

LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.

       LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.

       LIBSSH2_ERROR_SOCKET_TIMEOUT -

       LIBSSH2_ERROR_SFTP_PROTOCOL - An invalid SFTP protocol response was received on the socket,  or  an  SFTP
       operation caused an errorcode to be returned by the server.

       Number of bytes actually populated into buffer, or negative on failure.  It returns  LIBSSH2_ERROR_EAGAIN
       when  it  would  otherwise  block.  While  LIBSSH2_ERROR_EAGAIN  is a negative number, it is not really a
       failure per se.
