[c-prog] to clean screen

[ruhatadiyaman]

i want to clean screen in somewhere of my codes but 'clrscr()' does not work 
with #include<conio.h> . as i search it does not work in DEVC++(bloodshed). and 
i saw the system("cls") function which is declared in stdlib and it is working. 
is this a true way to clean screen?
best regards
