Lists the various error cases.

This enumeration lists the various error cases. When the application calls for a file system function which has a return type of SYS_FS_RESULT and if the return value is SYS_FS_RES_FAILURE, the application can know the specific reason for failure by calling the SYS_FS_FileError function.

The return value of SYS_FS_FileError function will be one of the enumeration of type SYS_FS_ERROR.

None.
