XmTextGetSubstringWcs(3) Library Functions Manual XmTextGetSubstringWcs(3) 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 ap- plication. 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 charac- ters from the beginning of the text buffer. The first charac- ter 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. For a complete definition of Text and its associated resources, see Xm- Text(3). RETURN XmCOPY_SUCCEEDED The function was successful. XmCOPY_FAILED The function failed because it was unable to copy the speci- fied 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 inter- nal 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.
