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)

fputws — put a wide-character string on a stream

---

Синопсис (Synopsis)

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

       int fputws(const wchar_t *restrict ws, FILE *restrict 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 fputws() function shall write a character string
       corresponding to the (null-terminated) wide-character string
       pointed to by ws to the stream pointed to by stream.  No
       character corresponding to the terminating null wide-character
       code shall be written.

       The last data modification and last file status change timestamps
       of the file shall be marked for update between the successful
       execution of fputws() and the next successful completion of a
       call to fflush() or fclose() on the same stream or a call to
       exit() or abort().

---

Возвращаемое значение (Return value)

Upon successful completion, fputws() shall return a non-negative
       number. Otherwise, it shall return -1, set an error indicator for
       the stream, and set errno to indicate the error.

Использование в приложениях (Application usage)

The fputws() function does not append a <newline>.

       This volume of POSIX.1‐2017 requires that successful completion
       simply return a non-negative integer. There are at least three
       known different implementation conventions for this requirement:

        *  Return a constant value.

        *  Return the last character written.

        *  Return the number of bytes written. Note that this
           implementation convention cannot be adhered to for strings
           longer than {INT_MAX} bytes as the value would not be
           representable in the return type of the function. For
           backwards-compatibility, implementations can return the
           number of bytes for strings of up to {INT_MAX} bytes, and
           return {INT_MAX} for all longer strings.
