This session starts with the C-Compilation process from system programmer perspective. The contents of intermediate files are discussed using readelf and objdump commands. The executable is loaded in gdb and the contents of CPU registers are shown. How a C program actually makes a system call is described in detail by making a system call with and without wrapper and finally calling a system call from within an assembly program.
