@chapter Input and Output (@file{stdio.h}) 

This chapter comprises functions to manage files
or other input/output streams. Among these functions are subroutines
to generate or scan strings according to specifications from a format string. 

The underlying facilities for input and output depend on the host
system, but these functions provide a uniform interface.

The corresponding declarations are in @file{stdio.h}.

The reentrant versions of these functions use macros

@example
_stdin_r(@var{reent})
_stdout_r(@var{reent})
_stderr_r(@var{reent})
@end example

@noindent
instead of the globals @code{stdin}, @code{stdout}, and
@code{stderr}.  The argument <[reent]> is a pointer to a reentrancy
structure.
