       XmTextFieldGetSubstringWcs  —  A TextField function that retrieves a portion of a wide character internal
       text buffer "XmTextFieldGetSubstring\%Wcs" "TextField functions" "XmTextFieldGetSubstring\%Wcs"

SYNOPSIS

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

DESCRIPTION

       XmTextFieldGetSubstringWcs retrieves a copy of a portion of the  internal  text  buffer  of  a  TextField
       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 TextField 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_t storage 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 to the end of the buffer and terminated the string with  a  NULL  terminator;  fewer
                 than num_chars characters were copied.
