Memory buffers are 2N/A * used to construct DOF to ioctl() to dtrace(7D), and provide semantics that 2N/A * simplify caller code. Specifically, any allocation errors result in an 2N/A * error code being set inside the buffer which is maintained persistently and 2N/A * propagates to another buffer if the buffer in error is concatenated. These 2N/A * semantics permit callers to execute a large series of writes without needing 2N/A * to check for errors and then perform a single check before using the buffer. 2N/A return;
