 standard/poll(2) -- input/output multiplexing
    The IRIX version of poll provides users with a mechanism for multiplexing input and output over a set of any type of file descriptors, rather than the traditional limitation to only descriptors of STREAMS devices [see select(2)]. Poll identifies those descriptors on which a user can send or receive messages, or on which certain events have occurred. Fds specifies the file descriptors to be examined and the events of interest for each file descriptor. It is a pointer to an array with one element ...
 standard/prctl(2) -- operations on a process
    prctl provides information about processes and the ability to control certain of their attributes. The return type ptrdiff_t is used so that prctl can return an integral value that is large enough to return a pointer/address. option specifies one of the following actions: PR_MAXPROCS returns the system imposed limit on the number of processes per user. PR_MAXPPROCS returns the maximum number of processors the calling process can utilize. If the caller is restricted ...
 standard/profil(2) -- execution time profile
    profil provides CPU-use statistics by profiling the amount of CPU time expended by a program. profil generates the statistics by creating an execution histogram for a current process. The histogram is defined for a specific region of program code to be profiled, and the identified region is logically broken up into a set of equal size subdivisions, each of which corresponds to a count in the histogram. With each clock tick, the current subdivision is identified and its corresponding histogram co...
 standard/ptrace(2) -- process trace
    ptrace allows a parent process to control the execution of a child process. Its primary use is for the implementation of breakpoint debugging [see dbx(1)]. The child process behaves normally until it encounters a signal [see signal(5)], at which time it enters a stopped state and its parent is notified via the wait(2) system call. When the child is in the stopped state, its parent can examine and modify its ``core image'' using pt<...
 standard/putmsg(2) -- send a message on a stream
    putmsg creates a message from user-specified buffer(s) and sends the message to a STREAMS file. The message may contain either a data part, a control part, or both. The data and control parts to be sent are distinguished by placement in separate buffers, as described below. The semantics of each part is defined by the STREAMS module that receives the message. The function putpmsg does the same thing as putmsg, but provides the user the abi...
 standard/quotactl(2) -- manipulate disk quotas
    The quotactl(2) call manipulates disk quotas for local EFS and XFS filesystems. cmd indicates a command to be applied to the user ID uid. special is a pointer to a null-terminated string containing the pathname of the block special device for the filesystem being manipulated. The block special device must be mounted as an EFS or XFS filesystem (see mount(2)). addr is the address of an optional, command specific data structure which is copied in or out of the system. The interpretation of addr is...
 standard/read(2) -- read from file
    read attempts to read nbyte bytes from the file associated with fildes into the buffer pointed to by buf. If nbyte is zero, read returns zero and has no other results. fildes is a file descriptor obtained from a creat, open, dup, fcntl, pipe, or ioctl system call. On devices capable of seeking, the read starts at a position in the file given by the file pointer associated with fildes...
 standard/readlink(2) -- read the value of a symbolic link
    readlink places the contents of the symbolic link referred to by path in the buffer buf, which has size bufsiz. The contents of the link are not null-terminated when returned. readlink fails and the buffer remains unchanged if: EACCES Search permission is denied for a component of the path prefix of path. EACCES Read permission is denied on the file named by path. EFAULT path or buf extends outs...
 standard/recv(2) -- receive a message from a socket
    Recv, recvfrom, and recvmsg are used to receive messages from a socket. The recv call is normally used only on a connected socket (see connect(2)), while recvfrom and recvmsg may be used to receive data on a socket whether it is in a connected state or not. If from is non-zero, the source address of the message is filled in. Fromlen is a value-result parameter, initialized to the size of the buffer associated with from, and modified on return to indicate the actual size of the address stored the...
 standard/rename(2) -- change the name of a file
    rename renames a file. old is a pointer to the pathname of the file or directory to be renamed. new is a pointer to the new pathname of the file or directory. Both old and new must be of the same type (either both files, or both directories) and must reside on the same file system. If new already exists, it is removed. Thus, if new names an existing directory, the directory must not have any entries other than, possibly, ``.'' and ``..''. When renaming directories,...
 standard/rexec(2) -- execute a file on a remote cell
    rexec in all its forms overlays a new process image on an old process and commences execution on a new cell. This system call was reserved to be supported in a future version of IRIX. In IRIX release 6.5, the only valid value for cell is 0 and then each form of rexec is equivalent to the corresponding form of exec. Therefore use of rexec is deprecated as this system call may not be present in future IRIX releases....
 standard/rmdir(2) -- remove a directory
    rmdir removes the directory named by the path name pointed to by path. The directory must not have any entries other than ``.'' and ``..''. If the directory's link count becomes zero and no process has the directory open, the space occupied by the directory is freed and the directory is no longer accessible. If one or more processes have the directory open when the last link is removed, the ``.'' and ``..'' entries, if present, are removed before r...
 standard/satctl(2) -- control the collection of audit data
    saton switches on collection of audit records of the specified event type. satoff switches off collection of audit records of the specified event type. satstate reports whether the audit subsystem is currently collecting or discarding records of the event type specified. To modify or query the audit state for every event type, call saton, satoff, or satstate repeatedly, once for each valid event type....
 standard/satgetid(2) -- get or set audit identity
    satgetid returns the audit identity of the calling process. satsetid sets the audit identify of the calling process. The calling process must have appropriate privilege to successfully call satgetid or satsetid. If _POSIX_CAP is in effect, appropriate privilege includes CAP_AUDIT_CONTROL capability.
 standard/satmp_done(2) -- de-register token-mapping daemon with kernel
    satmp_done de-registers the token-mapping daemon. The calling process must have appropriate privilege. If _POSIX_CAP is in effect, appropriate privilege includes CAP_NETWORK_MGT capability.
