static int System::File::chsize ( FILE *  fd, long  length  )

static

Changes file size.

Parameters

fd	File descriptor. Must be not NULL.
length	New file length.

Returns

Upon successful completion shall return 0; otherwise, -1 shall be returned and errno set to indicate the error.

Exceptions

System::Exception

if input parameters are incorrect.

static bool System::File::doesExist ( const std::string &  path )

static

Checks if the given file already exists.

Returns

true if so, otherwise false.

static std::string System::File::getCurrentDirectory ( )

static

Returns current directory path.

static long System::File::getNameMax ( const std::string &  path )

static

Returns the maximum number of bytes in the given filename.

Exceptions

static

Checks if the given file path is an absolute one.

Note

does not check if the file exists.

Returns

true if so, otherwise false.

static void System::File::setFlags ( int  aFd, int  aFlags  )

static

Sets the given file's flags.

Parameters

aFd	an open file descriptor.
aFlags	file status flags to turn on.

static void System::File::setOFileToMax ( )

static
