But i have read that C can have only one main function, so is this
valid?

Please always include the context of your message.

int main() {
main();
return 0;
}

There is only one instance of main() defined. It just happens to recursively
call itself.
Forever.

This, on the other hand, will eventually stop:

int num = 10;
int main() {
if ( --num > 0 ) {
main();
}
return 0;
}
