setitimer(2) -- get/set value of interval timer
|
|
The system provides each process with three interval timers, defined in . The getitimer() call returns the current value for the timer specified in which in the structure at value. The set... |
|
setlogin(2) -- get/set login name
|
|
The getlogin() routine returns the login name of the user associated with the current session, as previously set by setlogin(). The name is normally associated with a login shell at the time a session... |
|
|
setpgid(2) -- set process group
|
|
setpgid() sets the process group of the specified process pid to the specified pgrp. If pid is zero, then the call applies to the current process. If the invoker is not the super-user, then the affect... |
|
setpgrp(2) -- set process group
|
|
setpgid() sets the process group of the specified process pid to the specified pgrp. If pid is zero, then the call applies to the current process. If the invoker is not the super-user, then the affect... |
|
setpriority(2) -- get/set program scheduling priority
|
|
The scheduling priority of the process, process group, or user, as indicated by which and who is obtained with the getpriority() call and set with the setpriority() call. which is one of PRIO_PROCESS,... |
|
setregid(2) -- set real and effective group ID's
|
|
This interface is made obsolete by the saved ID functionality in setgid(2) and setegid(2). The real and effective group ID's of the current process are set according to the arguments. If the real gro... |
|
setreuid(2) -- set real and effective user ID's
|
|
This interface is made obsolete by the saved ID functionality in setuid(2) and seteuid(2). The real and effective user ID's of the current process are set according to the arguments. If the real user... |
|
setrlimit(2) -- control maximum system resource consumption
|
|
Limits on the consumption of system resources by the current process and each process it creates may be obtained with the getrlimit() call, and set with the setrlimit() call. Resources of an arbitrary... |
|
setsid(2) -- create session and set process group ID
|
|
The setsid function creates a new session. The calling process is the session leader of the new session, is the process group leader of a new process group and has no controlling terminal. The calling... |
|
setsockopt(2) -- get and set options on sockets
|
|
getsockopt() and setsockopt() manipulate the options associated with a socket. Options may exist at multiple protocol levels; they are always present at the uppermost ``socket'' level. When manipula... |
|
settimeofday(2) -- get/set date and time
|
|
Note: time zone information is no longer provided by this interface. See localtime(3) for information on how to retrieve it. The system's notion of the current UTC time is obtained with the gettimeof... |
|
setuid(2) -- set user and group ID
|
|
The setuid() function sets the real and effective user IDs and the saved set-user-ID of the current process to the specified value. The setuid() function is permitted if the specified ID is equal to t... |
|
shmat(2) -- map/unmap shared memory
|
|
shmat() maps the shared memory segment associated with the shared memory identifier shmid into the address space of the calling process. The address at which the segment is mapped is determined by the... |
|
shmctl(2) -- shared memory control operations
|
|
The shmctl() system call performs control operations on the shared memory segment specified by shmid. Each shared memory segment has a shmid_ds structure associated with it which contains the followin... |
|
shmdt(2) -- map/unmap shared memory
|
|
shmat() maps the shared memory segment associated with the shared memory identifier shmid into the address space of the calling process. The address at which the segment is mapped is determined by the... |
