The return section section of dlpi_recv(3DLPI) says:
Upon success, DLPI_SUCCESS is returned. If DL_SYSERR is
returned, errno contains the specific UNIX system error
value. Otherwise, a DLPI error value defined in <sys/dlpi.h>
or an error value listed in the following section is
returned.
Our code is busted with respect to the two level error codes. But in
contradiction with your statement this does say that at least dlpi_recv
could return an error via errno.
