Editor_LineFromChar

Retrieves the index of the line that contains the specified character index (the serial position). A character index is the zero-based index of the character from the beginning of the entire text. You can use this inline function or explicitly send the EE_LINE_FROM_CHAR message.

Editor_LineFromChar( HWND hwnd, int nLogical, UINT nSerialIndex );

Parameters
