I am currently trying to rehost some RJE software from System V.2 to ULTRIX 1.2. In this attempt I have run across a difference in the user structures between the two systems. In the System V.2 user structure there are the following declarations: unsigned u_count; /* Bytes remaining for I/O */ off_t u_offset; /* Offset in file for I/O */ The comments are from the System V.2 source for user.h. My question is does ULTRIX/4.2 have anything synonomous either in the user.h structure or some other place (uio.h maybe) that tracks with these declarations. any help will be greatly appreciated.. send replies to: cal@okc-unix

They are in the struct uio rather than the user structure. The UIO structure is built in the read and write routines in sys_generic and is passed along to the driver's read and write routines. -Ron
