standard/sync(2) -- update super block
|
|
sync causes all information in memory that should be on disk to be written out. This includes modified super blocks, modified i-nodes, and delayed block I/O. It should be used by programs that examine a file system, such as fsck(1M), df(1M), etc. It is mandatory before a re-boot. The writing, although scheduled, is not necessarily completed before sync returns. The fsync system call completes the writing before it returns.... |

standard/sysfs(2) -- get file system type information
|
|
sysfs returns information about the file system types configured in the system. The number of arguments accepted by sysfs varies and depends on the opcode. The currently recognized opcodes and their functions are: GETFSIND Translate fsname, a null-terminated file-system type identifier, into a file-system type index. GETFSTYP Translate fs_index, a file-system type index, into a nullterminated file-system type identifie... |

standard/sysget(2) -- Call for reading or writing kernel data
|
|
The sysget system call provides user access to kernel structures and tables on IRIX systems. sysget can return data for a combination of cpus, nodes, or cells depending on the combination of flags and cookie settings. The sysget system call accepts the following arguments: name Identifies the kernel structure or table. The sys/sysget.h file contains the list of names supported. Most come from the sysmp MP_SAGET options. Here is a partial list: SGT_SINFO SGT_MINFO SGT_DINFO SGT_SERR Returns the v... |
|
standard/sysinfo(2) -- get and set system information strings
|
|
sysinfo copies information relating to the UNIX system on which the process is executing into the buffer pointed to by buf; sysinfo can also set certain information where appropriate commands are available. count is the size of the buffer. The POSIX P1003.1 interface sysconf [see sysconf(2)] provides a similar class of configuration information, but returns an integer rather than a string. The commands available ... |
|
standard/sysmips(2) -- MIPS Computer Systems Inc. system call
|
|
sysmips is the interface to various machine specific functions. The cmd argument determines the function performed. The number of arguments expected is dependent on the function. |
|
standard/sysmp(2) -- multiprocessing control
|
|
sysmp provides control/information for miscellaneous system services. This system call is usually used by system programs and is not intended for general use. The arguments arg1, arg2, arg3, arg4 are provided for command-dependent use. As specified by cmd, the following commands are available: |
|
standard/syssgi(2) -- Silicon Graphics Inc. system call
|
|
syssgi is a system interface specific to Silicon Graphics systems. The value of the request parameter determines the meaning of the remaining arguments. In the descriptions below, arg1, arg2, and arg3 refer to parameters following the request argument. The following requests are currently supported: SGI_SYSID Returns an identifier for the given system. This identifier is guaranteed to be unique within the Silicon Graphics product family. The argument arg1 for this request should be a pointer to ... |
|
standard/time(2) -- get time
|
|
time returns the value of time in seconds since 00:00:00 UTC, January 1, 1970. If tloc is non-zero, the return value is also stored in the location to which tloc points. |
|
standard/times(2) -- get process and child process times
|
|
times fills the tms structure pointed to by buffer with time-accounting information. The tms structure is defined in <sys/times.h> as follows: struct tms { clock_t tms_utime; clock_t tms_stime; clock_t tms_cutime; clock_t tms_c... |
|
standard/truncate(2) -- set a file to a specified length
|
|
The file whose name is given by path or referenced by the descriptor fildes has its size set to length bytes. If the file was previously longer than length, bytes past length will no longer be accessible. If it was shorter, bytes from the EOF before the call to the EOF after the call will be read in as zeros. The effective user ID of the process must have write permission for the file, and for ftruncate and ftruncate64 the file must be ... |
|
standard/uadmin(2) -- administrative control
|
|
uadmin provides control for basic administrative functions. This system call is tightly coupled to the system administrative procedures and is not intended for general use. The argument mdep is provided for machine-dependent use and is not defined here. As specified by cmd, the following commands are available: A_SHUTDOWN The system is shut down. All user processes are killed, the buffer cache is flushed, and the root file system (and no other) is unm... |
|
standard/ulimit(2) -- get and set user limits
|
|
This function provides for control over process limits. The cmd values available are: UL_GETFSIZE Get the regular file size limit of the process. The limit is in units of 512-byte blocks and is inherited by child processes. Files of any size can be read. UL_SETFSIZE Set the regular file size limit of the process to the value of newlimit , taken as a long. newlimit is interpreted in units of 512-byte blocks. If, when converte... |
|
standard/umask(2) -- set and get file creation mask
|
|
umask sets the process's file mode creation mask to cmask and returns the previous value of the mask. Only the access permission bits of cmask and the file mode creation mask are used. |
|
standard/umount(2) -- unmount a file system
|
|
umount requests that a previously mounted file system contained on the block special device or directory identified by file be unmounted. file is a pointer to a path name. After unmounting the file system, the directory upon which the file system was mounted reverts to its ordinary interpretation. umount may be invoked only by a process with the super-user privilege. umount will fail if one or more of the following are true: EPER<... |
|
standard/uname(2) -- get name of current UNIX system
|
|
uname stores information identifying the current UNIX system in the structure pointed to by name. uname uses the structure utsname defined in <sys/utsname.h> whose members are: char sysname[SYS_NMLN]; char nodename[SYS_NMLN]; char release[... |
