globus_result_t globus_xio_attr_cntl | ( | attr | , |
driver | , | ||
GLOBUS_XIO_FILE_SET_MODE | , | ||
int | mode | ||
) |
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.
mode | A bitwise OR of all the modes desired |
string opt: mode=int
globus_result_t globus_xio_attr_cntl | ( | attr | , |
driver | , | ||
GLOBUS_XIO_FILE_GET_MODE | , | ||
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.
mode_out | The current mode will be stored here. |
globus_result_t globus_xio_attr_cntl | ( | attr | , |
driver | , | ||
GLOBUS_XIO_FILE_SET_FLAGS | , | ||
int | flags | ||
) |
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.
flags | A bitwise OR of all the flags desired |
string opt: flags=int
globus_result_t globus_xio_attr_cntl | ( | attr | , |
driver | , | ||
GLOBUS_XIO_FILE_GET_FLAGS | , | ||
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.
flags_out | The current flags will be stored here. |

GLOBUS_XIO_FILE_SET_TRUNC_OFFSET | , | ||
globus_off_t | offset | ||
) |
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)
offset | The desired size of the file. |
globus_result_t globus_xio_attr_cntl | ( | attr | , |
driver | , | ||
GLOBUS_XIO_FILE_GET_TRUNC_OFFSET | , | ||
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.
offset_out | The offset will be stored here. |

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

driver | , | ||
GLOBUS_XIO_FILE_SET_BLOCKING_IO | , | ||
globus_bool_t | use_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.
use_blocking_io | If GLOBUS_TRUE, true blocking io will be enabled. GLOBUS_FALSE will disable it (default); |

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