PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME

       clearerr -- clear indicators on a stream

SYNOPSIS

       #include <stdio.h>

       void clearerr(FILE *stream);

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.1-2008 defers to the ISO C standard.

       The clearerr() function shall clear the end-of-file and error indicators for the stream to which stream points.

       The clearerr() function shall not change the setting of errno if stream is valid.

RETURN VALUE

       The clearerr() function shall not return a value.

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.

PROLOG

NAME

       putwc -- put a wide character on a stream

SYNOPSIS

       #include <stdio.h>
       #include <wchar.h>

       wint_t putwc(wchar_t wc, FILE *stream);

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.1-2008 defers to the ISO C standard.

       The putwc() function shall be equivalent to fputwc(), except that if it is implemented as a macro it may evaluate stream more than once, so
       the argument should never be an expression with side-effects.

RETURN VALUE

       Refer to fputwc().

ERRORS

       Refer to fputwc().

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       Since it may be implemented as a macro, putwc() may treat a stream argument with side-effects incorrectly.  In  particular,  putwc(wc,*f++)
       need not work correctly. Therefore, use of this function is not recommended; fputwc() should be used instead.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
