NAME

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

SYNOPSIS

       #include <Xm/Text.h>

       int XmTextGetSubstringWcs (widget, start, num_chars, buffer_size, buffer)
	       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.  Specifies the Text widget ID.  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.  Specifies the number of wchar_t characters to be copied into the provided buffer.  Specifies the size of the sup-
       plied buffer as a number of wchar_t storage locations.  The minimum size is num_chars + 1.  Specifies the wide character buffer into  which
       the internal text buffer will be copied.

       For a complete definition of Text and its associated resources, see XmText(3X).

RETURN VALUE

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

NAME

       XmTextGetSubstring -- A Text function that retrieves a copy of a portion of the internal text buffer

SYNOPSIS

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

DESCRIPTION

       XmTextGetSubstring  retrieves  a  copy of a portion of the internal text buffer of a Text widget. 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.

       The  size of the required buffer depends on the maximum number of bytes per character (MB_CUR_MAX) for the current locale.  MB_CUR_MAX is a
       macro defined in stdlib.h. The buffer should be large enough to contain the substring to be copied and a NULL terminator. Use the following
       equation to calculate the size of buffer the application should provide:

       buffer_size = (num_chars* MB_CUR_MAX) + 1
       (void)

       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 characters to be copied into the provided buffer.

       buffer_size
		 Specifies the size of the supplied buffer in bytes. This size should account for a NULL terminator.

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

       For a complete definition of Text and its associated resources, see 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.
