| @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.
