Hi Everyone, I had a few problems in terms of understanding the method and method input parameters of the binary dumps created using otool and nm. Lets take the example of coretelephony class http://code.google.com/p/iphone-wireless/wiki/CoreTelephonyFunctions in this dump every method seems to be the same , i cannot differentiate how many input parameters each and every method taken. EX: _CTTelephonyCenterAddObserver - takes 4 arguments _CTCallAnswer - takes 1 argument How can be we find out this.When i try changing the input parameters also the ide does not warn me that this method with argument is invalid. Please help , i am stuck in this. Thnks .
