Topics you need to be familiar with: C Coding: - memory organization structs, unions, pointers pointers vs the data they point to arrays vs pointers strings vs character arrays (difference between strlen and sizeof) type as a format on memory - using memory malloc and free basic scoping and pointers difference between data on the stack and heap and accessing it size of things in memory and pointers initialization and declaration of variables - coding in practice read/fix code understand * and & understand void pointers understand pointer increment and array indexing understand pointer dereference and array indexing Shell commands: - basic vocabulary less, more, |, grep, top, ps, kill, man - file operations chmod and (to a lesser extent) chown both chmod argument types IO: - operation blocking vs non-blocking - in practice directories and files as you see them using readdir Processes: - basic fork, exec and Process lifecycle/anatomy aspects of/how to use fork and exec - Exceptional computation signals, what they are and how they work signals vs Exceptions
