|
|
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 superuser, then the affecte... |

|
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 superuser, then the affecte... |
|
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 IDs
|
|
The real and effective group IDs of the current process are set according to the arguments. If the real group ID is changed, the saved group ID is changed to the new value of the effective group ID. U... |
|
setresgid(2) -- get or set real, effective and saved user or group ID
|
|
The setresuid() function sets the real, effective and saved user IDs of the current process. The analogous setresgid() sets the real, effective and saved group IDs. Privileged processes may set these ... |
|
setresuid(2) -- get or set real, effective and saved user or group ID
|
|
The setresuid() function sets the real, effective and saved user IDs of the current process. The analogous setresgid() sets the real, effective and saved group IDs. Privileged processes may set these ... |
|
setreuid(2) -- set real and effective user IDs
|
|
The real and effective user IDs of the current process are set according to the arguments. If the real user ID is changed, or the effective user ID is changed to a value other than the real user ID, t... |
|
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. The resource parameter is... |
|
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: timezone is no longer used; this information is kept outside the kernel. The system's notion of the current Greenwich time and the current time zone is obtained with the gettimeofday() call, an... |
|
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 effective user ID is that ... |
|
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 some control operations on the shared memory area specified by shmid. Each shared memory segment has a data structure associated with it, parts of which may be altere... |
