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);
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.
