Standard C Library Functions                            wctob(3C)



NAME
     wctob - wide-character to single-byte conversion

SYNOPSIS
     #include 
     #include 

     int wctob(wintt 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  LCTYPE
     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.

ERORS
     No errors are defined.

ATRIBUTES
     See attributes(5) for descriptions of the  following  attri-
     butes:

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