\fBXmTextGetSubstringWcs\fP \(em A Text function that retrieves
a portion of a wide character internal text buffer

.SH "DESCRIPTION"
.PP
\fBXmTextGetSubstringWcs\fP 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\&.
.IP "\fIwidget\fP" 10
Specifies the Text widget ID\&.
.IP "\fIstart\fP" 10
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)\&.
.IP "\fInum_chars\fP" 10
Specifies the number of \fBwchar_t\fR characters to be copied into
the provided buffer\&.
.IP "\fIbuffer_size\fP" 10
Specifies the size of the supplied buffer as a number of \fBwchar_t\fR
storage locations\&. The minimum size is \fInum_chars\fP + 1\&.
.IP "\fIbuffer\fP" 10
Specifies the wide character buffer into which the internal
text buffer will be copied\&.
.PP

.SH "RETURN"
.IP "\fBXmCOPY_SUCCEEDED\fP" 10
The function was successful\&.
.IP "\fBXmCOPY_FAILED\fP" 10
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
\fIbuffer\fP are undefined\&.
.IP "\fBXmCOPY_TRUNCATED\fP" 10
The requested number of characters extended beyond the internal
buffer\&. The function copied characters between \fIstart\fP and the
end of the widget\&'s buffer and terminated the string with a NULL
terminator; fewer than \fInum_chars\fP characters were copied\&.
