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.
num_chars Specifies the number of wchart characters to be
copied into the provided buffer.
buffer_size
Specifies the size of the supplied buffer as a
number of wchart storage locations. The minimum
size is num_chars + 1.
buffer Specifies the wide character buffer into which the
internal text buffer will be copied.
