Hi Jalal,
It returns the number of free (available) transmit buffers. This number will vary depending on how many blocks you send and where the Media Engine is regarding sending the blocks.
The first time you call the GetNumIvrTxBuffers() proc, the number it returns will be the maximum number of tx buffers available. As you send blocks of data the number returned by the GetNumIvrTxBuffers() proc will be reduced. If the GetNumIvrTxBuffers() proc returns a value of 0, then your application code must wait for data blocks to be transmitted by the media engine before you can try to send more.
