4.4. Creating and Opening Files
[4. Implementation Design]

The library provides functions to create, open, and close files. Each function uses or fills in a variable of type xid which identifies the file to the API.

The "xid" type is the same type as HDF5’s hid_t. Variables of type xid are used to access all files, groups, and arrays stored in XMDF files.

C/C++

int xfCreateFile(const char *Name, xid *FileId, xbool Overwrite);
int xfOpenFile(const char *Name, xid *FileId, xbool Readonly);
int xfCloseFile(xid FileId);
