RSetErrLock()

Sets the status of the error lock mechanism to true or false.

Synopsis

void RSetErrLock( bool lock);

Parameters


Parameter	Description
lock	TRUE = Set the error lock FALSE = Do not set the error lock.

Description

Sets the status of the error lock mechanism to true or false. Every function of the R control extension can set the error status to a value unequal to 0 if an error has occurred. If the error status is already unequal to 0 when an R control extension function is called, the execution of the function is skipped and the error status is not modified if the error lock mechanism is active.

Example

In this example an error status is created and then cleared.

#uses "CtrlR"
main()
{
  int userData = 3; /*Sets the userData parameter to identify errors, see RLoadModel()*/
  RSetErrLock(1); //Sets the error lock, see RSetErrLock()
  REvalExp(userData, "1/0"); //Causes an error
  DebugN(REvalExp(userData, "1+1"));//The debug cannot be executed
  RClearErr(); //clears the error
  DebugN(REvalExp(userData, "1+1"));//the debug is executed
}
