 NAME

wctob - wide-character to single-byte conversion

 SYNOPSIS

 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 behaviour of this function is affected by the LC_CTYPE category of the current locale.
