Summary

MineSingleBuffer fills the buffer with consecutive tagged signaling NaNs.

Pascal

 procedure MineSingleBuffer(var Buffer; Count: Integer; StartTag: TNaNTag = 0);

Parameters

Parameters	Description
var Buffer	The buffer to initialize with SNaN values.
Count: Integer	The number of array elements.
StartTag: TNaNTag = 0	The integer value assigned to the first array element. The tag is increased with each subsequent array element.

Description

MineSingleBuffer fills the buffer with consecutive tagged signaling NaNs. This allows for real number arrays which enforce initialization: any attempt to load an uninitialized array element into the FPU will raise an exception either of class EJclNaNSignal (Windows NT) or EInvalidOp (else). Under Windows NT thus the violating array index can be derived from the EJclNaNSignal object's Tag property.
