## Define Documentation

### #define GLOBUS\_XIO\_FILE\_INVALID\_HANDLE

Invalid handle type. **See also:**

**GLOBUS\_XIO\_FILE\_SET\_HANDLE**

## Enumeration Type Documentation

### enum globus\_xio\_file\_flag\_t

File driver open flags

OR together all the flags you want. **See also:**

**GLOBUS\_XIO\_FILE\_SET\_FLAGS**

**Enumerator:**

- *GLOBUS\_XIO\_FILE\_CREAT*

  *Create a new file if it doesn't exist (default)*

- *GLOBUS\_XIO\_FILE\_EXCL*

  *Fail if file already exists.*

- *GLOBUS\_XIO\_FILE\_RDONLY*

  *Open for read only.*

- *GLOBUS\_XIO\_FILE\_WRONLY*

  *Open for write only.*

- *GLOBUS\_XIO\_FILE\_RDWR*

  *Open for reading and writing (default)*

- *GLOBUS\_XIO\_FILE\_TRUNC*

  *Truncate file.* **See also:**

  **GLOBUS\_XIO\_FILE\_SET\_TRUNC\_OFFSET**

- *GLOBUS\_XIO\_FILE\_APPEND*

  *Open file for appending.*

- *GLOBUS\_XIO\_FILE\_BINARY*

  *File is binary (default)*

- *GLOBUS\_XIO\_FILE\_TEXT*

  *File is text.*

### enum globus\_xio\_file\_mode\_t

*File driver create mode*

*OR these modes together to get the mode you want.* **See also:**

**GLOBUS\_XIO\_FILE\_SET\_MODE**

*NOTE: for Win32, you only have a choice between read-only and read-write. If the chosen mode does not specify writability, the file will be read only*

**Enumerator:**

- *GLOBUS\_XIO\_FILE\_IRWXU*

  *User read, write, and execute.*

- *GLOBUS\_XIO\_FILE\_IRUSR*

  *User read.*

- *GLOBUS\_XIO\_FILE\_IWUSR*

  *User write.*

- *GLOBUS\_XIO\_FILE\_IXUSR*

  *User execute.*

- *GLOBUS\_XIO\_FILE\_IRWXO*

  *Others read, write, and execute.*

- *GLOBUS\_XIO\_FILE\_IROTH*

  *Others read.*

- *GLOBUS\_XIO\_FILE\_IWOTH*

  *Others write.*

- *GLOBUS\_XIO\_FILE\_IXOTH*

  *Others execute.*

- *GLOBUS\_XIO\_FILE\_IRWXG*

  *Group read, write, and execute.*

- *GLOBUS\_XIO\_FILE\_IRGRP*

  *Group read.*

- *GLOBUS\_XIO\_FILE\_IWGRP*

  *Group write.*

- *GLOBUS\_XIO\_FILE\_IXGRP*

  *Group execute.*

### enum globus\_xio\_file\_whence\_t

*File driver seek options.* **See also:**

**GLOBUS\_XIO\_FILE\_SEEK**

**Enumerator:**

- *GLOBUS\_XIO\_FILE\_SEEK\_SET*

  *set the file pointer at the specified offset*

- *GLOBUS\_XIO\_FILE\_SEEK\_CUR*

  *set the file pointer at current position + offset*

- *GLOBUS\_XIO\_FILE\_SEEK\_END*

  *set the file pointer at size of file + offest*
