NOTES

The ferror() function may be a macro (depending on the compile-time definitions used in the source).  Consequently, you cannot use this interface where a function is necessary; for example, a subroutine pointer cannot point to it. 

AES Support Level:
Full use.

RETURN VALUES

If an I/O error occurred when reading from or writing to the stream specified by the stream parameter, a nonzero value is returned.  Otherwise, a value of 0 (zero) is returned.
