standard/kill(2) -- send a signal to a process or a group of processes
|
|
kill sends a signal to a process or a group of processes. The process or group of processes to which the signal is to be sent is specified by pid. The signal that is to be sent is specified by sig and is either one from the list given in signal(2), or 0. If sig is 0 (the null signal), error checking is performed but no signal is actually sent. This can be used to check the validity of pid. The real or effective user ID of the sending process must match the real, saved, or effective user ID of th... |

standard/link(2) -- link to a file
|
|
path1 points to a path name naming an existing file. path2 points to a path name naming the new directory entry to be created. link creates a new link (directory entry) for the existing file and increments its link count by one. Upon successful completion, link marks for update the st_ctime field of the file. Also, the st_ctime and st_mtime fields of the directory that contains the new entry are marked for upd... |

standard/listen(2) -- listen for connections on a socket
|
|
To accept connections, a socket is first created with socket(2), a willingness to accept incoming connections and a queue limit for incoming connections are specified with listen(2), and then each new connection is accepted with accept(2). The listen call applies only to sockets of type SOCK_STREAM. The backlog parameter defines the maximum length the queue of pending connections. If a connection request arrives with the queue full the client may receive an error with an indication of ECONNREFUS... |

standard/lseek(2) -- move read/write file pointer
|
|
fildes is a file descriptor returned from a creat, open, dup, fcntl, pipe, or ioctl system call. lseek and lseek64 set the file pointer associated with fildes as follows: If whence is SEEK_SET, the pointer is set to offset bytes. If whence is SEEK_CUR, the pointer is set to its current location plus offset. If whence is SEEK_E<... |

standard/madvise(2) -- give advice about handling memory
|
|
madvise provides the system advice about the process' expected use of its address space from addr to addr + len. The following types of behavior are currently recognized by the system: MADV_DONTNEED informs the system that the address range from addr to addr + len will likely not be referenced in the near future. The memory to which the indicated addresses are mapped will be the first to be reclaimed when memory is needed by the system. madvise will fail if: [ENOMEM] Addresses in the range (add... |
|
standard/memcntl(2) -- memory management control
|
|
NOTE: this function is not currently implemented in IRIX. Any calls to this function will return ENOSYS. The function memcntl allows the calling process to apply a variety of control operations over the address space identified by the mappings established for the address range [addr, addr + len). addr must be a multiple of the pagesize as returned by sysconf(3C). The scope of the control operations can be further defined with additional selection criteri... |
|
standard/mkdir(2) -- make a directory
|
|
mkdir creates a new directory with the name path. The mode of the new directory is initialized from mode (see chmod(2) for values of mode]. The protection part of mode is modified by the process's mode mask (see umask(2)). The S_ISGID, S_ISUID, and S_ISVTX bits are silently deleted from mode. The directory's owner ID is set to the process's effective user ID. The directory's group ID is set to the process's effective group ID or the grou... |
|
standard/mkfifo(2) -- make a FIFO special file
|
|
The mkfifo routine creates a new FIFO special file named by the pathname pointed to by path. IRIX implements it via the following mknod call: mknod(path, (mode | S_IFIFO), 0) where S_IFIFO is defined in . Refer to mknod(2) for details. |
|
standard/mknod(2) -- make a directory, or a special or ordinary file
|
|
mknod creates a new file named by the path name pointed to by path. The mode of the new file (including file type bits) is initialized from mode. The value of the file type bits which are permitted with this system call are those listed below. The other types listed in sys/stat.h are made with other system calls, or are not supported by this operating system. S_IFIFO fifo special S_IFCHR character special S_IFBLK block special S_IFREG ordinary file All other mode bits are interpreted as describe... |
|
standard/mmap(2) -- map pages of memory
|
|
The functions mmap and mmap64 establish a mapping between a process's address space and a virtual memory object. The format of the call is as follows: pa = mmap(addr, len, prot, flags, fd, off); mmap establishes a mapping between the process's address space at an address pa for len bytes to the memory object represented by the file descriptor fd at offset off for len bytes. The value of pa is an implementation-depend... |
|
standard/mount(2) -- mount a file system
|
|
mount requests that a removable file system contained on the block special file identified by spec be mounted on the directory identified by dir. spec and dir are pointers to path names. fstyp is the file system type number. The sysfs(2) system call can be used to determine the file system type number. If both the MS_DATA and MS_FSS flag bits of mflag are off, the file system type defaults to the root file system type. Only if either... |
|
standard/mpin(2) -- lock pages in memory
|
|
mpin reads into memory all pages over the range (addr, addr + len), and locks the pages into memory. Associated with each locked page is a counter which is incremented each time the page is locked. The superuser can lock as many pages as it wishes, other users are limited to a configurable per process maximum. munpin decrements the lock counter associated with the pages over the range (addr, addr + len). Pages whose counters are zero are available to be swapped out ... |
|
standard/mprotect(2) -- set protection of memory mapping
|
|
The function mprotect changes the access protections on the mappings specified by the range [addr, addr + len) to be that specified by prot. Legitimate values for prot are the same as those permitted for mmap and are defined in <sys/mman.h> as: PROT_READ /* page can be read */ PROT_WRITE /* page ca... |
|
standard/msgctl(2) -- message control operations
|
|
msgctl provides a variety of message control operations as specified by cmd. The following cmds are available: IPC_STAT Place the current value of each member of the data structure associated with msqid into the structure pointed to by buf. The contents of this structure are defined in intro(2). IPC_SET Set the value of the following members of the data structure associated with msqid to the corresponding value found in the ... |
|
standard/msgget(2) -- get message queue
|
|
msgget returns the message queue identifier associated with key. A message queue identifier and associated message queue and data structure [see intro(2)] are created for key if one of the following are true: key is IPC_PRIVATE. key does not already have a message queue identifier associated with it, and (msgflg&IPC_CREAT) is true. On creation, the data structure associated with the new message queue identi... |
