static Standard_EXPORT void | SetSignal (const Standard_Boolean aFloatingSignal=Standard_True) |
1) Arms some floating point signals, and sets a "Handler" for them. 2) Sets a "Handler" for the "Hardware" signals. For Win32 users: under VC++ you can control which method of handling exceptions is used by means of UseSETranslator method before calling SetSignal | |
static Standard_EXPORT Standard_Integer | AvailableMemory () |
Returns available memory in Kilobytes. . | |
static Standard_EXPORT Standard_Boolean | SetLocale (const Standard_CString aString1, const Standard_CString aString2) |
Changes the program's current locale . | |
static Standard_EXPORT void | SecSleep (const Standard_Integer aDelay) |
Commands the process to sleep for a number of seconds. . | |
static Standard_EXPORT void | MilliSecSleep (const Standard_Integer aDelay) |
Commands the process to sleep for a number of milliseconds . | |
static Standard_EXPORT Standard_Boolean | RealToCString (const Standard_Real aReal, Standard_PCharacter &aString) |
Converts aReal into aCstring in exponential format with a period as decimal point, no thousand separator and no grouping of digits. The conversion is independant from the current locale . | |
static Standard_EXPORT Standard_Boolean | CStringToReal (const Standard_CString aString, Standard_Real &aReal) |
Converts aCstring representing a real with a period as decimal point, no thousand separator and no grouping of digits into aReal . The conversion is independant from the current locale. . | |
static Standard_EXPORT Standard_Boolean | IsDivisible (const Standard_Real aDividend, const Standard_Real aDivisor) |
Tests if the quotient theDividend/theDivisor does not overflow . | |
static Standard_EXPORT Standard_Integer | GetExponent (const Standard_Real aReal) |
Returns the exponent in base 2 of a floating-point number. . | |
static Standard_EXPORT Standard_Real | GetMantissa (const Standard_Real aReal) |
Returns the mantissa of a floating-point number. . | |
static Standard_EXPORT void | ControlBreak () |
since Windows NT does not support 'SIGINT' signal like UNIX, then this method checks whether Ctrl-Break keystroke was or not. If yes then raises Exception_CTRL_BREAK. | |
static Standard_EXPORT void | UseSETranslator (const Standard_Boolean useSE) |
Defines whether SetSignal must use _se_translator_function or SetUnhandledExceptionFilter and signal to catch system exceptions. The default behaviour is to use SE translator. Warning: Using SE translator method SetSignal should be called for each new created thread, while using the alternative method the exception handler is established once for the whole process and all its threads. This function takes effect only under VC++ compiler. . | |
static Standard_EXPORT Standard_Boolean | UseSETranslator () |
Returns the current value of the flag set by above method. . | |

static Standard_EXPORT void | Handler (const OSD_Signals aSignal, const Standard_Address aSigInfo, const Standard_Address aContext) |
static Standard_EXPORT void | SegvHandler (const OSD_Signals aSignal, const Standard_Address aSigInfo, const Standard_Address aContext) |
static Standard_EXPORT Standard_Integer | WntHandler (const Standard_Address exceptionInfo) |
1) Raises an exception if the exception due to floating point errors. Flosting point errors: EXCEPTION_FLT_DENORMAL_OPERAND EXCEPTION_FLT_DIVIDE_BY_ZERO EXCEPTION_FLT_INEXACT_RESULT EXCEPTION_FLT_INVALID_OPERATION EXCEPTOPN_FLT_OVERFLOW EXCEPTION_FLT_STACK_CHECK EXCEPTION_FLT_UNDERFLOW 2) Displays a message box 'Continue' - 'Debugger' - 'Stop' if the environment variable 'CSF_EXCEPTION_PROMPT' is set and takes appropriate action. Raises an exception otherwise. |
