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.
