The &mfunc function returns the integer value of the next
multibyte-character in
.arg string,
without advancing the string pointer.
&mfunc recognizes multibyte character sequences according to the
multibyte code page currently in use.
.np
The header file
.hdrfile tchar.h
defines the generic-text routine
.kw _tcsnextc.
This macro maps to &mfunc if
.kw _MBCS
has been defined, or to &wfunc if
.kw _UNICODE
has been defined.
Otherwise
.kw _tcsnextc
maps to &func..
&func and &wfunc are single-byte character string and wide-character
string versions of &mfunc..
&func and &wfunc are provided only for this mapping and should not be
used otherwise.
&func returns the integer value of the next single-byte character in
the string.
&wfunc returns the integer value of the next wide character in the
string.
.desc end
.return begin
These functions return the integer value of the next character
(single-byte, wide, or multibyte) pointed to by
.arg string.
