File API

Functions relating to the File API.

The functions prefaced with Ipcf rather than Ipc are a subset of the SDK and are the File API.

Note

For error condition processing, always use a call to IpcGetErrorMessageText right after an SDK API call fails, so you get complete information about the nature of the error.
