XmTextGetSubstringWcs(Xm) 6 January 1993 XmTextGetSubstringWcs(Xm) Name XmTextGetSubstringWcs - a Text function that retrieves a portion of a wide character internal text buffer Syntax #include <Xm/Text.h> int XmTextGetSubstringWcs (widget, start, num_chars, buffer_size, buffer) 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 posi- tion 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. numchars Specifies the number of wchart characters to be copied into the provided buffer. buffersize Specifies the size of the supplied buffer as a number of wchart storage locations. The minimum size is numchars + 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 XmText(Xm). Return value XmCOPYSUCCEEDED The function was successful. XmCOPYFAILED 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. XmCOPYTRUNCATED 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 ter- minator; fewer than numchars characters were copied.
