Typedefs
typedef void(*	EGS_InfoFunction) (const char *,...)
	Defines a function printf-like prototype for functions to be used to report info, warnings, or errors.

Enumerations
enum	EGS_InfoType { Information , Warning , Fatal }

Functions
bool EGS_EXPORT	egsStoreI64 (ostream &data, EGS_I64 n)
	Writes the 64 bit integer n to the output stream data and returns true on success, false on failure. More...
bool EGS_EXPORT	egsGetI64 (istream &data, EGS_I64 &n)
	Reads a 64 bit integer from the stream data and assigns it to n. Returns true on success, false on failure. More...
EGS_InfoFunction EGS_EXPORT	egsSetInfoFunction (EGS_InfoType t, EGS_InfoFunction func)
	Set a function to be used for outputing information, warning messages or reporting fatal errors. More...
void EGS_EXPORT	egsSetDefaultIOFunctions ()
	Reset I/O functions to their defaults.
string EGS_EXPORT	egsSimplifyCVSKey (const string &key)
	Remove the $'s from a CVS key. More...
void EGS_EXPORT	egsSwapBytes (int *)
	Swap the bytes of 32 bit integers.
void EGS_EXPORT	egsSwapBytes (short *)
	Swap the bytes of 16 bit integers.
void EGS_EXPORT	egsSwapBytes (float *)
	Swap the bytes of 32 bit reals.
string EGS_EXPORT	egsJoinPath (const string &first, const string &second)
	Join two path variables (or a path and a file name) using the platform specific directory separator and return the result.
string EGS_EXPORT	egsStripPath (const string &fname)
	Strip the path from a file name and return the result.
string EGS_EXPORT	egsExpandPath (const string &fname)
	Expands first environment variable found in a file name. More...
string EGS_EXPORT	egsHostName ()
	Get the name of the host the program is running on.
int EGS_EXPORT	egsGetPid ()
	Get the process id.
int EGS_EXPORT	egsGetEndian ()
	Get the endianess of the machine. More...
bool EGS_EXPORT	egsIsAbsolutePath (const string &path)
	Does the string path represent an absolute path name?
bool EGS_EXPORT	egsEquivStr (const string &a, const string &b)

Variables
const EGS_Float	epsilon = 1.0/(1ULL<<50)
	The epsilon constant for floating point comparisons. More...
const EGS_Float	distanceEpsilon = 1.0/(1ULL<<32)
	The distanceEpsilon constant for physical distance comparisons. More...
const EGS_I64	loopMax = 1e10
	The maximum number of iterations for near-infinite loops. More...
const EGS_Float	veryFar = 1e30
	A very large float. More...
EGS_EXPORT EGS_InfoFunction	egsInformation
	Always use this function for reporting the progress of a simulation and any other type of information. More...
EGS_EXPORT EGS_InfoFunction	egsWarning
	Always use this function for reporting warnings. More...
EGS_EXPORT EGS_InfoFunction	egsFatal
	Always use this function for reporting fatal errors. More...
