TUnixSystem
Class providing an interface to the UNIX Operating System.
TUnixSystem() : TSystem("Unix", "Unix System")
~TUnixSystem()
Reset to original state.
Bool_t Init()
Initialize Unix system interface.
void SetProgname(const char *name)
Set the application name (from command line, argv[0]) and copy it in
gProgName. Copy the application pathname in gProgPath.
void SetDisplay()
Set DISPLAY environment variable based on utmp entry. Only for UNIX.
const char* GetError()
Return system error string.
const char* HostName()
Return the system's host name.
void AddFileHandler(TFileHandler *h)
Add a file handler to the list of system file handlers.
TFileHandler* RemoveFileHandler(TFileHandler *h)
Remove a file handler from the list of file handlers.
void AddSignalHandler(TSignalHandler *h)
Add a signal handler to list of system signal handlers.
TSignalHandler* RemoveSignalHandler(TSignalHandler *h)
Remove a signal handler from list of signal handlers.
void ResetSignal(ESignals sig, Bool_t reset)
If reset is true reset the signal handler for the specified signal
to the default handler, else restore previous behaviour.
void IgnoreSignal(ESignals sig, Bool_t ignore)
If ignore is true ignore the specified signal, else restore previous
behaviour.
void DispatchOneEvent(Bool_t pendingOnly)
Dispatch a single event.
void Sleep(UInt_t milliSec)
Sleep milliSec milliseconds.
void DispatchSignals(ESignals sig)
Handle and dispatch signals.
Bool_t CheckSignals(Bool_t sync)
Check if some signals were raised and call their Notify() member.
void CheckChilds()
Check if childs have finished.
Bool_t CheckDescriptors()
Check if there is activity on some file descriptors and call their
Notify() member.
int MakeDirectory(const char *name)
Make a Unix file system directory. Returns 0 in case of success and
-1 if the directory could not be created.
void* OpenDirectory(const char *name)
Open a Unix file system directory. Returns 0 if directory does not exist.
void FreeDirectory(void *dirp)
Close a Unix file system directory.
const char* GetDirEntry(void *dirp)
Get next Unix file system directory entry. Returns 0 if no more entries.
Bool_t ChangeDirectory(const char *path)
Change directory. Returns kTRUE in case of success, kFALSE otherwise.
const char* WorkingDirectory()
Return working directory.
const char* HomeDirectory(const Char_t *userName)
Return the user's home directory.
char* ConcatFileName(const char *dir, const char *name)
Concatenate a directory and a file name. Returned string must be
deleted by user.
Bool_t AccessPathName(const char *path, EAccessMode mode)
Returns FALSE if one can access a file using the specified access mode.
Mode is the same as for the Unix access(2) function.
Attention, bizarre convention of return value!!
void Rename(const char *f, const char *t)
Rename a file.
int GetPathInfo(const char *path, Long_t *id, Long_t *size,
Long_t *flags, Long_t *modtime)
Get info about a file: id, size, flags, modification time.
Id is (statbuf.st_dev << 24) + statbuf.st_ino
Size is the file size
Flags is file type: 0 is regular file, bit 0 set executable,
bit 1 set directory, bit 2 set special file
(socket, fifo, pipe, etc.)
Modtime is modification time.
The function returns 0 in case of success and 1 if the file could
not be stat'ed.
int GetFsInfo(const char *path, Long_t *id, Long_t *bsize,
Long_t *blocks, Long_t *bfree)
Get info about a file system: id, bsize, bfree, blocks.
Id is file system type (machine dependend, see statfs())
Bsize is block size of file system
Blocks is total number of blocks in file system
Bfree is number of free blocks in file system
The function returns 0 in case of success and 1 if the file system could
not be stat'ed.
int Link(const char *from, const char *to)
Create a link from file1 to file2. Returns 0 when successful,
-1 in case of failure.
int Symlink(const char *from, const char *to)
Create a symlink from file1 to file2. Returns 0 when succesfull,
-1 in case of failure.
int Unlink(const char *name)
Unlink, i.e. remove, a file or directory. Returns 0 when succesfull,
-1 in case of failure.
Bool_t ExpandPathName(TString &path)
Expand a pathname getting rid of special shell characters like ~.$, etc.
For Unix/Win32 compatibility use $(XXX) instead of $XXX when using
environment variables in a pathname. If compatibility is not an issue
you can use on Unix directly $XXX.
Bool_t ExpandPathName(TString &patbuf0)
Expand a pathname getting rid of special shell characters like ~.$, etc.
For Unix/Win32 compatibility use $(XXX) instead of $XXX when using
environment variables in a pathname. If compatibility is not an issue
you can use on Unix directly $XXX.
char* ExpandPathName(const char *path)
Expand a pathname getting rid of special shell characaters like ~.$, etc.
For Unix/Win32 compatibility use $(XXX) instead of $XXX when using
environment variables in a pathname. If compatibility is not an issue
you can use on Unix directly $XXX. The user must delete returned string.
int Umask(Int_t mask)
Set the process file creation mode mask.
int Utime(const char *file, Long_t modtime, Long_t actime)
Set a files modification and access times. If actime = 0 it will be
set to the modtime. Returns 0 on success and -1 in case of error.
char* Which(const char *search, const char *wfil, EAccessMode mode)
Find location of file "wfil" in a search path.
The search path is specified as a : separated list of directories.
User must delete returned string. Returns 0 in case file is not found.
void Setenv(const char *name, const char *value)
Set environment variable. The string passed will be owned by
the environment and can not be reused till a "name" is set
again. The solution below will lose the space for the string
in that case, but if this functions is not called thousands
of times that should not be a problem.
const char* Getenv(const char *name)
Get environment variable.
int Exec(const char *shellcmd)
Execute a command.
FILE* OpenPipe(const char *command, const char *mode)
Open a pipe.
int ClosePipe(FILE *pipe)
