fputwc(3) OSS Library Calls Reference Manual

NAME

fputwc - Writes a wide character to a speciﬁed stream

LIBRARY

G-series native OSS processes: /G/system/sysnn/zcrtlsrl

H-series and J-series native Guardian processes: $SYSTEM.ZDLLnnn.ZCRTLDLL

SYNOPSIS For TNS/E Target Compilations on H06.09 and Later RVUs

This version of the function applies to TNS/E target compilations on H06.09 and later H-series

RVUs.

#include <wchar.h>

wint_t fputwc(

wchar_t c,

FILE *stream);

SYNOPSIS For Other RVUs

This version of the function applies to TNS/R target compilations and to TNS/E target compila-

tions on H06.08 and earlier H-series RVUs.

#include <wchar.h>

wint_t fputwc(

wint_t c,

FILE *stream);

PARAMETERS

c Speciﬁes the wide character to be written. The data type of this parameter

depends on the target compilation and the RVU the system is running:

• If the target is TNS/R or if the target is TNS/E and the system is running

H06.08 or an earlier H-series RVU, the data type of this parameter can

be either wint_t or wchar_t.

• If the target is TNS/E and the system is running H06.09 or a later H-

series RVU, the data type of this parameter must be wchar_t. If you

have an existing object ﬁle compiled from source text that speciﬁes a

value of type wint_t for this parameter, you can continue to use the

object ﬁle. However, if you recompile the same source text, the com-

piler converts the wint_t value to a wchar_t value and issues a warning

message.

stream Points to the output data.

DESCRIPTION

The fputwc( ) function converts the wchar_t speciﬁed by the c parameter to its equivalent multi-

byte character and then writes the multibyte character to the stream parameter.

The fputwc( ) function works the same as putwc( ).

With the exception of stderr, output streams are, by default, buffered if they refer to ﬁles, or line

buffered if they refer to terminals. The standard error output stream, stderr, is unbuffered by

default, but using the freopen( ) function causes it to become buffered or line buffered. Use the

setbuf( ) function to change the stream’s buffering strategy.
