globus_result_t globus_xio_attr_cntl (attr, driver, \fBGLOBUS_XIO_FILE_SET_MODE\fP, intmode)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the file create mode.

Use this to set the permissions a non-existent file is created with, The default mode is 0644.

Parameters:

mode A bitwise OR of all the modes desired

string opt: mode=int

globus_result_t globus_xio_attr_cntl (attr, driver, \fBGLOBUS_XIO_FILE_GET_MODE\fP, int *mode_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 file create mode.

Parameters:

mode_out The current mode will be stored here.

globus_result_t globus_xio_attr_cntl (attr, driver, \fBGLOBUS_XIO_FILE_SET_FLAGS\fP, intflags)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the file open flags.

The default flags specify to create the file if it doesn't exist, open it for reading and writing, and interpret it as a binary file.

Parameters:

flags A bitwise OR of all the flags desired

string opt: flags=int

globus_result_t globus_xio_attr_cntl (attr, driver, \fBGLOBUS_XIO_FILE_GET_FLAGS\fP, int *flags_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 file open flags.

Parameters:

flags_out The current flags will be stored here.

globus_result_t globus_xio_attr_cntl (attr, driver, \fBGLOBUS_XIO_FILE_SET_TRUNC_OFFSET\fP, 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 the file truncate offset.

Use this in conjunction with the GLOBUS_XIO_FILE_TRUNC flag to truncate a file to a non-zero offset. If the file was larger than offset bytes, the extra data is lost. If the file was shorter or non-existent, it is extended and the extended part reads as zeros. (default is 0)

Parameters:

offset The desired size of the file.

globus_result_t globus_xio_attr_cntl (attr, driver, \fBGLOBUS_XIO_FILE_GET_TRUNC_OFFSET\fP, globus_off_t *offset_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 file truncate offset.

Parameters:

offset_out The offset will be stored here.

globus_result_t globus_xio_attr_cntl (attr, driver, \fBGLOBUS_XIO_FILE_SET_HANDLE\fP, globus_xio_system_file_thandle)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the file handle to use.

Do not open a new file, use this pre-opened handle instead.

Parameters:

handle Use this handle (fd or HANDLE) for the file. Note: close() will not be called on this handle.

globus_result_t globus_xio_attr_cntl (attr, driver, \fBGLOBUS_XIO_FILE_GET_HANDLE\fP, globus_xio_system_file_t *handle_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 file handle in use or in attr.

Parameters:

handle_out The file handle (fd or HANDLE) will be stored here. If none is set, GLOBUS_XIO_TCP_INVALID_HANDLE will be set.

globus_result_t globus_xio_attr_cntl (attr, driver, \fBGLOBUS_XIO_FILE_SET_BLOCKING_IO\fP, globus_bool_tuse_blocking_io)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Enable true blocking io when making globus_xio_read/write() calls. Note: use with caution. You can deadlock an entire app with this.

Parameters:

use_blocking_io If GLOBUS_TRUE, true blocking io will be enabled. GLOBUS_FALSE will disable it (default);

globus_result_t globus_xio_attr_cntl (attr, driver, \fBGLOBUS_XIO_FILE_GET_BLOCKING_IO\fP, globus_bool_t *use_blocking_io_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 blocking io status in use or in attr.

Parameters:

use_blocking_io_out The flag will be set here. GLOBUS_TRUE for enabled.

string opt: blocking=bool

globus_result_t globus_xio_handle_cntl (handle, driver, \fBGLOBUS_XIO_FILE_GET_HANDLE\fP, globus_xio_system_file_t *handle_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 file handle in use or in attr.

Parameters:

handle_out The file handle (fd or HANDLE) will be stored here. If none is set, GLOBUS_XIO_TCP_INVALID_HANDLE will be set.

globus_result_t globus_xio_handle_cntl (handle, driver, \fBGLOBUS_XIO_FILE_SET_BLOCKING_IO\fP, globus_bool_tuse_blocking_io)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Enable true blocking io when making globus_xio_read/write() calls. Note: use with caution. You can deadlock an entire app with this.

Parameters:

use_blocking_io If GLOBUS_TRUE, true blocking io will be enabled. GLOBUS_FALSE will disable it (default);

globus_result_t globus_xio_handle_cntl (handle, driver, \fBGLOBUS_XIO_FILE_GET_BLOCKING_IO\fP, globus_bool_t *use_blocking_io_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 blocking io status in use or in attr.

Parameters:

use_blocking_io_out The flag will be set here. GLOBUS_TRUE for enabled.

string opt: blocking=bool

globus_result_t globus_xio_handle_cntl (handle, driver, \fBGLOBUS_XIO_FILE_SEEK\fP, globus_off_t *in_out_offset, \fBglobus_xio_file_whence_t\fPwhence)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Reposition read/write file offset.

Parameters:

in_out_offset Specify the desired offset (according to whence). On success, the actual file offset will be stored here.

whence Specify how offset should be interpreted.
