reading fprintf statements from console in qt

[KrishnaKishan]

Hi,
we have many fprintf statements in our project written in a c function. This c function is getting called by qt class. So the fprintf statements coming in console should be read line by line and show in QTextEdit in append mode. We are not using QProcess also, just calling a c function having many fprintf statements.
Pls suggest me how can i read the each fprintf statement once it is written to console and the same text should be shown in QTextEdit in our project?
