@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.
