  MBLKP unlinkb(
	  MBLKP message_ptr );

ARGUMENTS
  message_ptr
      Specifies a pointer to the message block from which the first message
      block is to be removed. The typedef MBLKP is an alternate name for
      typedef struct msgb *.

  block pointed to by the message_ptr argument. The interface returns a
  pointer to the new message block, minus the removed message block.
