Error Handling for Input/Output Functions
Errors
on
file access are
indicated by the return value of the file access function. When the
end of a file is encountered by a read function, for example, the
symbolic constant EOF (for byte-oriented files) or
WEOF (for wide-oriented files) is returned. If a
read or write error has occurred, an error flag is also set in the
FILE structure.
Furthermore, in reading or writing wide-oriented streams, errors can
occur in the conversion between wide characters of type
wchar_t and multibyte characters in the stream.
This is the case if one of the conversion functions
mbrtowc() and wcrtomb() does
not return a permissible value. The global error variable
errno then has the value EILSEQ
(“error: illegal sequence”).
