SenseByte

Unit:SDL_dstruct
Class:TFifo
Declaration:function SenseByte (ix: longint; var OutByte: byte): boolean;

It is sometimes useful to read any byte in the FIFO without deleting the information (as it is done by GetByte). The method SenseByte reads a byte at the specified position ix and returns it in the parameter OutByte. The value of OutByte is only valid if the function returned a TRUE value.

The index ix is relative to the output of the FIFO. An index of ix =0 points to the oldest byte in the FIFO. The parameter ix may receive values between 0 and CountBytes -1.
