Enumerator
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
string opt: blocking=bool
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
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
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
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
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
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
See also
string opt: flags=int
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
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
See also
string opt: mode=int
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
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
string opt: blocking=bool
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
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
See also
GLOBUS_XIO_SEEK
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.
