NAME

     btowc -- convert a single byte character to a wide character


LIBRARY

SYNOPSIS

     #include <wchar.h>

DESCRIPTION

     The btowc() function converts a single byte character c in the initial
     shift state of the current locale to a corresponding wide character.

     The behaviour of btowc() is affected by the LC_CTYPE category of the cur-
     rent locale.


RETURN VALUES

     The btowc() function returns:

     WEOF          If c is EOF or if (unsigned char) c does not correspond to
                   a valid single byte character representation.

     (otherwise)   A wide character corresponding to c.


ERRORS

     No errors are defined.
