30 Host and process identifiers
51 Each process is largely independent of other processes,
55 Each process in a host is named by an integer
56 called the \fIprocess id\fP. This number is
65 in a multi-host environment, the (hostid, process id) pairs are
68 Process creation and termination
70 A new process is created by making a logical duplicate of an
71 existing process:
76 The \fIfork\fP call returns twice, once in the parent process, where
77 \fIpid\fP is the process identifier of the child,
78 and once in the child process where \fIpid\fP is 0.
82 A process may terminate by executing an \fIexit\fP call:
89 When a child process exits or
90 terminates abnormally, the parent process receives
92 event which caused termination of the child process. A
94 to retrieve information about resources consumed by the process during its
107 A process can overlay itself with the memory image of another process,
108 passing the newly created process a set of parameters, using the call:
115 the execution of a specified interpreter program to process its contents.
119 Each process in the system has associated with it two user-id's:
122 Each process has an \fIreal accounting group id\fP and an \fIeffective
126 Each process may be in several different access groups, with the maximum
131 The real and effective user ids associated with a process are returned by:
180 Process groups
182 Each process in the system is also normally associated with a \fIprocess
183 group\fP. The group of processes in a process group is sometimes
186 The current process group of a process is returned by the
192 When a process is in a specific process group it may receive
195 In particular, a system terminal has a process group and only processes
196 which are in the process group of the terminal may read from the
199 The process group associated with a process may be changed by
205 Newly created processes are assigned process id's distinct from all
206 processes and process groups, and the same process group as their
207 parent. A normal (unprivileged) process may set its process group equal
208 to its process id. A privileged process may set the process group of any
209 process to any value.
