 standard/cachectl(2) -- mark pages cacheable or uncacheable
    The cachectl system call allows a process to make ranges of its address space cacheable or uncacheable. Initially, a process's entire address space is cacheable. The op parameter may be one of: CACHEABLE Make the indicated pages cacheable UNCACHEABLE Make the indicated pages uncacheable The CACHEABLE and UNCACHEABLE op's affect the address range indicated by addr and nbytes. addr must be page aligned and nbytes must be a multiple of the page size. Changing a page from UNCACHEABLE state to CACH...
 standard/cacheflush(2) -- flush contents of instruction and/or data cache
    cacheflush and _flush_cache are different names for the same function. They flush the contents of the indicated cache(s) for user addresses in the range addr to (addr+nbytes-1). The cache parameter may be one of: ICACHE Flush only the instruction cache DCACHE Flush only the data cache BCACHE Flush both the instruction and the data cache
 standard/chdir(2) -- change working directory
    chdir and fchdir cause a directory pointed to by path or fildes to become the current working directory, the starting point for path searches for path names not beginning with /. path points to the path name of a directory. The fildes argument to fchdir is an open file descriptor of a directory. In order for a directory to become the current directory, a process must have execute (search) access to the directory. chdir will fai...
 standard/chmod(2) -- change mode of file
    chmod and fchmod set the access permission portion of the mode of the file whose name is given by path or referenced by the descriptor fildes to the bit pattern contained in mode. If path or fildes are symbolic links, the access permissions of the target of the symbolic links are set. Access permission bits are interpreted as follows: S_ISUID 04000 Set user ID on execution. S_ISGID 020#0 Set group ID on execution if # is 7, ...
 standard/chown(2) -- change owner and group of a file
    Path points to a path name naming a file, and fd refers to the file descriptor associated with a file. The owner ID and group ID of the named file are set to the numeric values contained in owner and group respectively. Note that lchown differs from chown in that it does not follow symbolic links. Only processes with effective user ID equal to the file owner or superuser may change the ownership of a file. However, if the variable restricted_chown is enabled [see intro(2) and lboot(1M)] then onl...
 standard/chroot(2) -- change root directory
    path points to a path name naming a directory. chroot causes the named directory to become the root directory, the starting point for path searches for path names beginning with /. The user's working directory is unaffected by the chroot system call. The calling process must have the super-user privilege to change the root directory. The .. entry in the root directory is interpreted to mean the root directory itself. Thus, .. cannot be used to ...
 standard/clock_settime(2) -- get/set date and time (POSIX)
    The clock_settime() function sets the specific clock, clock_id, to the value specified by tp. Time values that are between two consecutive nonnegative integer multiples of the resolution of the specified clock are truncated down to the smaller multiple of the resolution. The clock_gettime() function returns the current value tp for the specified clock, clock_id. Depending on the clocks resolution, it may be possi...
 standard/close(2) -- close a file descriptor
    fildes is a file descriptor obtained from a creat, open, dup, fcntl, pipe, or iocntl system call. close closes the file descriptor indicated by fildes. All outstanding record locks owned by the process (on the file indicated by fildes) are removed. If the link count of the file is zero, when all file descriptors associated with the file have been closed, the space occupied by the file is freed and the...
 standard/comp(2) -- data stream compression and uncompression
    The comp library and associated system calls allows applications to use the compression and decompression algorithms from compress(1) and uncompress(1) directly, without having to invoke a separate executable. The compression code in this library has been optimized, and if used in combination with large buffer file reading can result in improved compression times of up to 30% over the standard compress code. You must link with the comp library: cc -o prog prog.c -lcomp...
 standard/connect(2) -- initiate a connection on a socket
    The parameter s is a socket. If it is of type SOCK_DGRAM, then this call specifies the peer with which the socket is to be associated; this address is that to which datagrams are to be sent, and the only address from which datagrams are to be received. If the socket is of type SOCK_STREAM, then this call attempts to make a connection to another socket. The other socket is specified by name, which is an address in the communications space of the socket. Each communications space interprets the na...
 standard/creat(2) -- create a new file or rewrite an existing one
    creat creates a new ordinary file or prepares to rewrite an existing file named by the path name pointed to by path. If the file exists, the length is truncated to 0 and the mode and owner are unchanged. If the file does not exist the file's owner ID is set to the effective user ID of the process. The group ID of the file is set to the effective group ID of the process or to the group ID of the directory in which the file is being created. This is determined as follows: If the un...
 standard/dev_to_devname(2) -- determine the device name for the device
    dev_to_devname is useful to determine the canonical hardware graph path name given the device identifier.
 standard/dev_to_drivername(2) -- determine the driver name for the device
    dev_to_drivername is useful to determine the name of the driver handling the device.
 standard/dmi(2) -- DMAPI internal system call
    dmi is a system interface specific to Silicon Graphics systems. It is used to implement the interface defined in the X/Open document: Systems Management: Data Storage Management (XDSM) API dated February 1997. This interface is available made available on Silicon Graphics systems by means of the libdm library. The value of the opcode parameter determines the meaning of the remaining arguments. These are all interfaces that are used to implement various libdm functions. The only filesystem that s...
 standard/dup(2) -- duplicate an open file descriptor
    fildes is a file descriptor obtained from a creat, open, dup, fcntl, pipe, or ioctl system call. dup returns a new file descriptor having the following in common with the original: Same open file (or pipe). Same file pointer (i.e., both file descriptors share one file pointer). Same access mode (read, write or read/write). The new file descriptor is set to remain open across exec system calls [see ...
