wctob(3C)						   Standard C Library Functions 						 wctob(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.

NOTES

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

NAME

       wctob - wide-character to single-byte conversion

SYNOPSIS

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

       int wctob(wint_t c);

DESCRIPTION

       The wctob() function shall determine 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 shall be affected by the LC_CTYPE category of the current locale.

RETURN VALUE

       The  wctob()  function  shall  return EOF if c does not correspond to a character with length one in the initial shift state. Otherwise, it
       shall return the single-byte representation of that character as an unsigned char converted to int.

ERRORS

       No errors are defined.
