(l) Implementation definition
(m) Error indicator and end-of-file indicator
(n) File position indicator
Definitions differ depending on compilers.
The following two data items are held for each stream file:
(1) an error indicator that indicates whether or not an error has occurred during file
input/output, and
(2) an end-of-file indicator that indicates whether or not the input file has ended.
These data items can be referenced by the ferror function and the feof function,
respectively.
With some functions that handle stream files, error occurrence and end-of-file information
cannot be obtained from the return value alone. The error indicator and end-of-file
indicator are useful for checking the file status after execution of such functions.
Stream files that can be read or written at any position within the file, such as disk files,
have an associated data item called a file position indicator that indicates the current
read/write position within the file.
File position indicators are not used with stream files that do not permit the read/write
position within the file to be changed, such as terminals.
