standard/statvfs(2) -- get file system information
|
|
statvfs returns a ``generic superblock'' describing a file system; it can be used to acquire information about mounted file systems. buf is a pointer to a structure (described below) that is filled by the system call. path should name a file that resides on that file system. The file system type is known to the operating system. Read, write, or execute permission for the named file is not required, but all directories listed in the path name leading to the file must be sea... |
|
standard/stime(2) -- set time
|
|
stime sets the system's idea of the time and date. tp points to the value of time as measured in seconds from 00:00:00 UTC January 1, 1970. stime will fail if: EPERM the calling process does not have the super-user privilege. |

standard/swapctl(2) -- manage swap space
|
|
swapctl adds, deletes, or returns information about swap resources. Swap resources can be local disk partitions (block devices), local file system files, and files on file systems mounted via nfs. cmd specifies one of the following options contained in <sys/swap.h>: SC_ADD /* add a resource for swapping */ SC_LIST /* l... |

standard/symlink(2) -- make a symbolic link to a file
|
|
symlink creates a symbolic link name2 to the file name1. Either name may be an arbitrary pathname, the files need not be on the same file system, and name1 may be nonexistent. The file to which the symbolic link points is used when an open(2) operation is performed on the link. A stat(2) on a symbolic link returns the linked-to file, while an lstat returns information about the link itself. This can lead to surprising results when a sym... |
|
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... |
