Syscall()

No need to call directly. Class only contains static functions.

Public Methods

static	access(string, AccessMode) : int Checks whether the calling task has the necessary access rights to perform operations specified by mode on the file pathname. AccessMode is a mask consisting of one or more of the values R_OK, W_OK, X_OK and F_OK which respectively test if the taks can read, write, execute or test if the file exists.
static	alarm(uint) : uint If the call completes successfully, the taks will receive a SIGALARM signal after a delay of seconds seconds. A delay of zero seconds simply cancel the alarm. If an previous alarm was activated when the call is made then the previous alarm is cancelled.
static	chdir(string) : int Changes the current directory to 'path'.
static	chmod(string, FileMode) : int Change permissions for a file or folder.
static	chown(string, int, int) : int Change owner for a file or folder.
static	chroot(string) : int Change root directory
static	close(int) : int Closes the file descriptor fileDescriptor. If fileDescriptor is the last file descriptor refering to a file, then the ressources associated with that file are deallocated. The lock held on the file by the current task are released.
static	closedir(IntPtr) : int Closes the directory represented by IntPtr. IntPtr is a pointer retrieved by opendir()
static	creat(string, FileMode) : int Creates a file 'pathname' using the given file mode flags.
static	dup(int) : int dup duplicates a file descriptor to the lowest unused file descriptor available.
static	dup2(int, int) : int dup2 duplicates a file descriptor to another specified file descriptor. If the destination file descriptor is already used, it is closed. The two descriptors share all (ie. file locks, position, etc.) but the close-on-exec flag.
static	exit(int) : int Terminates the process that calls the function with the status 'status'.
static	fork() : int fork() turns a single process into 2 identical processes, known as the parent and the child.
static	getegid() : int Get the effective group ID for the current process.
static	geteuid() : int Get the effective user ID for the current process.
static	getgid() : int Get the group ID for the current process.
static	getgroupname(int) : string Retrieve the groupname for the given GID.
static	gethostname() : string Retrieves the hostname.
static	GetHostName() : string Retrieves the hostname.
static	getpgrp() : int Get the process group.
static	getpid() : int Returns the unique identifier for the current process.
static	getppid() : int Returns the unique identifier for the parent process.
static	getuid() : int Get the user ID for the current process.
static	getusername(int) : string Retrieves the username for the UID in question.
static	isatty(int) : bool Boolean value indicating if the file at fileDescriptor is a tty.
static	kill(int, int) Kill the process 'pid' with the given signal.
static	lchown(string, int, int) : int Change the ownership for 'path'
static	link(string, string) : int Create a hard link from oldPath to newPath.
static	lseek(int, int, int) : int Changes the read/write file offset of a file descriptor.
static	lstat(string, out Stat) : int Retrieves via output paramter the file status struct for a file.
static	mkdir(string, FileMode) : int Create a directory at 'path' with the given FileMode.
static	nice(int) : int Change the priority of the current process by given increment.
static	open(string, OpenFlags) : int Creates/opens a file 'pathname' using the given file open flags.
static	open(string, OpenFlags, FileMode) : int Creates/opens a file 'pathname' using the given open and file mode flags.
static	opendir(string) : IntPtr Opens a directory at 'path'.
static	pause() : int Pause the current process. The task sleeps until a signal is received.
static	read(int, void*, IntPtr) : IntPtr Reads up to count bytes into buf from fileDescriptor.
static	readdir(IntPtr) : string Read entry from a directory IntPtr as string.
static	readlink(string) : string Gets the destination of a symlink as a string. See also read()
static	rename(string, string) : int Rename oldPath to newPath.
static	rmdir(string) : int Removes the directory at 'path'.
static	setgid(int) : int Sets the group ID for the current process to 'gid'.
static	setpgid(int, int) : int Sets the process group ID for the current process to 'pgid'.
static	setregid(int, int) : int Sets the real and effective group ID for the current process to 'rgid' and 'egid' respectively.
static	setreuid(int, int) : int Sets the real and effective user ID for the current process to 'ruid' and 'euid' respectively.
static	setsid() : int Creates a session and sets the process group ID.
static	setuid(int) : int Sets the user ID for the current process to 'uid'.
static	signal(int, Syscall.sighandler_t) : int Register a handler for a given posix signal.
static	stat(string, out Stat) : int Retrieves via output paramter the file status struct for a file.
static	strerror(int) : string Get error message string for 'errnum'.
static	symlink(string, string) : int Create a soft link from oldPath to newPath.
static	sync() sync forces "dirty" (modified) filesystem buffers to be written to disk.
static	umask(int) : int Sets new umask.
static	unlink(string) : int Deletes a link to a file.
static	waitpid(int, WaitOptions) : int waitpid() will force a parent process to wait for a child process to stop or terminate.
static	waitpid(int, out int, WaitOptions) : int waitpid() will force a parent process to wait for a child process to stop or terminate.
static	WEXITSTATUS(int) : int WIFEXITSTATUS is a method that take an argument status, of type int, as returned by waitpid().
static	WIFEXITED(int) : int WIFEXITED is a method that take an argument status, of type int, as returned by waitpid().
static	WIFSIGNALED(int) : int WIFSIGNALED is a method that take an argument status, of type int, as returned by waitpid().
static	WIFSTOPPED(int) : int WIFSTOPPED is a method that take an argument status, of type int, as returned by waitpid().
static	write(int, void*, IntPtr) : IntPtr write writes up to 'count' bytes to the file referenced by the file descriptor 'fileDescriptor' from the buffer starting at 'buf'.
static	WSTOPSIG(int) : int WSTOPSIG is a method that take an argument status, of type int, as returned by waitpid().
static	WTERMSIG(int) : int WTERMSIG is a method that take an argument status, of type int, as returned by waitpid().
