== Why is this an issue?

This includes file and I/O functions ``++fgetpos++``, ``++fopen++``, ``++ftell++``, ``++gets++``, ``++perror++``, ``++remove++``, ``++rename++`` and ``++ungetc++``.


Streams and file I/O have a large number of unspecified, undefined and implementation-defined behaviors associated with them. It is assumed within MISRA C that they will not normally be needed in production code in embedded systems.


If any of the features of ``++stdio.h++`` need to be used in production code, then the issues associated with the features need to be understood.


=== Noncompliant code example

[source,cpp]
----
#include <stdio.h> /* Noncompliant */
