     NAME
          XmTextGetSubstringWcs - A Text function that retrieves a
          portion of a wide character internal text buffer

     SYNOPSIS
          #include <Xm/Text.h>
          int XmTextGetSubstringWcs(
          Widget widget,
          XmTextPosition start,
          int num_chars,
          int buffer_size,
          wchar_t *buffer);

     VERSION
          This page documents Motif 2.1.

     DESCRIPTION
          XmTextGetSubstringWcs retrieves a copy of a portion of the
          internal text buffer of a Text widget that is stored in a
          wide character format. The function copies a specified
          number of characters from a given start position in the
          internal text buffer into a buffer provided by the
          application. A NULL terminator is placed at the end of the
          copied data.

          widget    Specifies the Text widget ID.

          start     Specifies the beginning character position from
                    which the data will be retrieved. This is an
                    integer number of characters from the beginning of
                    the text buffer. The first character position is 0
                    (zero).

          num_chars Specifies the number of wchar_t characters to be
                    copied into the provided buffer.

          buffer_size
                    Specifies the size of the supplied buffer as a
                    number of wchar_tstorage locations. The minimum
                    size is num_chars + 1.

          buffer    Specifies the wide character buffer into which the
                    internal text buffer will be copied.

     RETURN
          XmCOPY_SUCCEEDED
                    The function was successful.

          XmCOPY_FAILED
                    The function failed because it was unable to copy
                    the specified number of characters into the buffer
                    provided.  The buffer size may be insufficient.
                    The contents of buffer are undefined.

          XmCOPY_TRUNCATED
                    The requested number of characters extended beyond
                    the internal buffer. The function copied
                    characters between start and the end of the
                    widget's buffer and terminated the string with a
                    NULL terminator; fewer than num_chars characters
                    were copied.
