OK what have you done so far?

As we agree the first code you gave in #1 wont take you very far...

Passing numbers, OK but what if its not the case? like char or words, what happens?

Writing a script that accepts arguments is something nice, but unless its for your own usage, it should be fool proof and properly written Like :

No argument -> display usage

Testing the argument values etc...

Function Documentation globus_result_t globus_xio_handle_cntl (handle, driver, GLOBUS_XIO_ORDERING_SET_OFFSET, globus_off_toffset) This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set offset for the next IO operation. This is not allowed when there is an outstanding IO operation. This operation clears all the buffered data. Parameters: offset Specifies the offset to use in the next IO operation. globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_SET_MAX_READ_COUNT, intmax_read_count) This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the maximum number of reads that ordering driver can have outstanding on driver(s) below. Parameters: max_read_count Specifies the maximum number of parallel reads (default is 1). globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_GET_MAX_READ_COUNT, int *max_read_count_out) This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the maximum number of parallel reads set on the attr. Parameters: max_read_count_out The maximum number of parallel reads allowed will be stored here. globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_SET_BUFFERING, globus_bool_tbuffering) This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. This driver can be used in 2 modes; ordering (care about offsets of the data read - underlying transport driver may deliver data out of order - this driver will rearrange data based on the offset and deliver inorder to user) and buffering (do not care about offsets - just buffer the data read abd deliver it when requested). This attribute control can be used to enable buffering. Parameters: buffering GLOBUS_TRUE to enable buffering, GLOBUS_FALSE (default) to disable buffering. globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_GET_BUFFERING, globus_bool_t *buffering_out) This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the buffering flag on the attr. Parameters: buffering_out Buffering flag will be stored in here. globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_SET_BUF_SIZE, intbuf_size) This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the size of the buffer that ordering driver creates to use for reading data from the driver below it. Parameters: buf_size Specifies the buffer size for internal reads (default is 100 KB). globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_GET_BUF_SIZE, int *buf_size_out) This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the size of the buffer used for the internal reads. Parameters: buf_size_out The buffer size will be stored in here. globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_SET_MAX_BUF_COUNT, intmax_buf_count) This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the maximum number of buffers that this driver can create for reading data from the driver below it. Parameters: max_buf_count Specifies the max buffer count for internal reads (default is 100). globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_GET_MAX_BUF_COUNT, int *max_buf_count_out) This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the maximum buffer count set on the attr. Parameters: max_buf_count_out The maximun buffer count will be stored in here.
