XmTextGetSubstringWcs(3)

NAME

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

SYNOPSIS

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

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_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.

   XmText(3).

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.
