Hi, I needed an idea about the sequence of function calls that occur when the user-level library call socket(,,) is made. For instance, if I wanted to modify the number of parameters being passed to this call, what functions should I be looking at in the kernel to modify? What is the first kernel function called in response to the 0x80 interrupt for this call? Which is the function call in the entry.S file for this library call... I must say that a book like W. Richard Stevens TCP/IP Vol 2 for linux networking would have been great...the commentary book isn't detailed enough, esp about the interface, about the relationships between the user library and the kernel interface.... Help! Hari - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.rutgers.edu
