Standard C Library Functionswctob(3C)


NAME

 wctob - wide-character to single-byte conversion

SYNOPSIS

 
#include <stdio.h>
#include <wchar.h>
int wctob(wint_t c);

DESCRIPTION

 

The wctob() function determines whether c corresponds to a member of the extended character set whose character representation is a single byte when in the initial shift state.

The behavior of this function is affected by the LC_CTYPE category of the current locale. See environ(5)

RETURN VALUES

 

The wctob() function returns EOF if c does not correspond to a character with length one in the initial shift state. Otherwise, it returns the single-byte representation of that character.

ERRORS

 

No errors are defined.

ATTRIBUTES

 

See attributes(5) for descriptions of the following attributes:

NOTES

 

The wctob() function can be used safely in multithreaded applications, as long as setlocale(3C) is not being called to change the locale.
