Detailed Description

Most functions in this file return an IoOpReport that details the success or failure of their actions.

Note

All functions in this header that require a file to be opened handle the opening and closing of the file automatically. The file will be reopened in the correct mode if it is already opened, and the file will always be closed when the function returns.
