You first met Mahmoud Saleh in an episode of C9::GoingNative covering CRT (C Run-time Library). Mahmoud is the keeper of the CRT(C Run-time Library) at Microsoft, working on the VC++ team as a software engineer. The information presented in that GoingNative episode was introductory in nature and as we expected you asked for more advanced treatment of this important subject matter. Well, being the kind person that he is, Mahmoud agreed to do a full lecture covering advanced topics related to CRT. Thank you, Mahmoud!
