ANSI_SYNOPSIS
|
|
#include <stdio.h>
|
|
void rewind(FILE *<[fp]>);
|
|
void _rewind_r(struct _reent *<[ptr]>, FILE *<[fp]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
#include <stdio.h>
|
|
void rewind(<[fp]>)
|
|
FILE *<[fp]>;
|
|
|
|
void _rewind_r(<[ptr]>, <[fp]>)
|
|
struct _reent *<[ptr]>;
|
|
FILE *<[fp]>;
|
|
|
|
DESCRIPTION
|
|
<<rewind>> returns the file position indicator (if any) for the file
|
|
or stream identified by <[fp]> to the beginning of the file. It also
|
|
clears any error indicator and flushes any pending output.
|
|
|
|
RETURNS
|
|
<<rewind>> does not return a result.
|
|
|
|
PORTABILITY
|
|
ANSI C requires <<rewind>>.
|
|
|
|
No supporting OS subroutines are required.
