Detailed Description

This class implements the most common Unix system calls.

Public Methods
void	getKernelInfo ()
	This method will update the name and information about the current running kernel.
const char *	getUnixName ()
	Use this method to retreives the name of the UNIX version you are currently using.
const char *	getNodeName ()
	This method will give you the nodename of your current host machine.
const char *	getKernelRelease ()
	This will return your current kernel release string.
const char *	getKernelReleaseVersion ()
	This will return your current kernel release version string.
const char *	getHostMachine ()
	This will return your current architecture description.
const char *	getClassName ()
	Returns the name of the current class.
Static Public Methods
int	getuid ()
	Obtains the current (running) user id.
int	getuid (const String &username)
	Obtain uid from username.
int	getgid ()
	Obtains the current (running) user id.
int	getgid (const String &groupname)
	Obtain uid from username.
int	chown (const String &fname, int userid, int groupid=-1)
	Changes the owner of the file by its numeric userid.
int	chown (const String &fname, const String &owner)
	Changes the owner of the file by its username.
int	chgrp (const String &fname, int userid)
	Changes the group owner of the file by its numeric userid.
int	chgrp (const String &fname, const String &groupname)
	Changes the group owner of the file by its groupname.
int	installedCPUs ()
	This will return how many CPUs are installed in the system.
double	cpuSpeed ()
	This will return the CPU speed in megahertz.
int	totalMemory ()
	Will return the total amount of system memory.
int	freeMemory ()
	Will return the total amount of free system memory.
void	usleep (Uint32 usec)
	Will freeze the software for usec microseconds.
Protected Methods
void	setClassName (const char *n)
	Call this method when you need to set the name of the class you're creating, typically in it's constructor, remember that you must set the classname for every class you create, that way you can have more information while debugging.
Protected Attributes
char *	sysname
	Pointer to system name.
