The state of a single thread is thus very similar to that of a process. It has a program counter (PC) that tracks where the program is fetching instructions from Unix System Calls and Posix Threads Overview Process-related Unix system calls Posix threads 2 Process-related Unix System Calls A process in U nix consists of an address space and one thread Unix provides several process-related system calls:
