Function `ilclient_get_input_buffer` will return Null when the third parameter (block) is 0 and there is temporarily no buffer available in the free list. Calling `ilclient_get_input_buffer` with "block" turned-on should prevent the caller from getting Null pointer repeatedly. Thus, the program won't suffer the "Got NULL buffer" error.
