Пролог (Prolog)
This manual page is part of the POSIX Programmer's Manual. The
Linux implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior),
or the interface may not be implemented on Linux.
Имя (Name)
rewind — reset the file position indicator in a stream
Синопсис (Synopsis)
#include <stdio.h>
void rewind(FILE *stream);
Описание (Description)
The functionality described on this reference page is aligned
with the ISO C standard. Any conflict between the requirements
described here and the ISO C standard is unintentional. This
volume of POSIX.1‐2017 defers to the ISO C standard.
The call:
rewind(stream)
shall be equivalent to:
(void) fseek(stream, 0L, SEEK_SET)
except that rewind() shall also clear the error indicator.
Since rewind() does not return a value, an application wishing to
detect errors should clear errno, then call rewind(), and if
errno is non-zero, assume an error has occurred.
Возвращаемое значение (Return value)
The rewind() function shall not return a value.
Ошибки (Error)
Refer to fseek(3p) with the exception of [EINVAL] which does not
apply.
