Member Function Documentation

mpcl::text::TString mpcl::system::TSystem::getCurrentDirectory (  void    )  const [virtual]

Get current directory. Returns: Current directory. Exceptions: std::bad_alloc  If there is no memory available. Implements mpcl::system::ISystem. Definition at line 82 of file posix_1/system.cc. References mpcl::text::TString.

char mpcl::system::TSystem::getDirectorySeparator (  void    )  const [virtual]

Get symbol for directory separator. Returns: The directory separator. Implements mpcl::system::ISystem. Definition at line 138 of file posix_1/system.cc.

std::size_t mpcl::system::TSystem::getFileSize (  const char *    pkcFILE_NAME )  const throw (TErrorException) [virtual]

Get file size. Parameters: pkcFILE_NAME  File name. Returns: Size of pkcFILE_NAME. Implements mpcl::system::ISystem. Definition at line 117 of file posix_1/system.cc. References mpcl::system::GetErrorMessage().

char mpcl::system::TSystem::getPathSeparator (  void    )  const [virtual]

Get symbol for path separator. Returns: The path separator. Implements mpcl::system::ISystem. Definition at line 145 of file posix_1/system.cc.

int mpcl::system::TSystem::getProcessId (  void    )  const [virtual]

Gets an unique integer value that identifies the current process. Returns: The process identifier. Implements mpcl::system::ISystem. Definition at line 75 of file posix_1/system.cc.

void mpcl::system::TSystem::sleep (  std::size_t    zSECONDS, std::size_t    zNANOSECONDS = 0 )  const [virtual]

Sleeps zSECONDS seconds and zNANOSECONDS nanoseconds. According to POSIX.1, sleep() affect only to the current thread. Parameters: zSECONDS  Seconds to wait. zNANOSECONDS  Nanoseconds to wait. Implements mpcl::system::ISystem. Definition at line 57 of file posix_1/system.cc.

void mpcl::system::TSystem::yield (  void    )  const [virtual]

Yields yield the processor. A process can relinquish the processor voluntarily without blocking by calling yield(). The process will then be moved to the end of the queue for its static priority and a new process gets to run. See also: std::sched_yield(). Implements mpcl::system::ISystem. Definition at line 68 of file posix_1/system.cc.
