ANSITAPE(1M) Merlin ANSITAPE(1M)
Note to Systems Programmers
ansitape uses a boolean function (eot) to determine when the tape drive has hit
the end of file. It is called every time a block of data is written to
the tape. If this function ever returns TRUE (a defined constant), an
automatic volume switch occurs. The pertinent device registers are
obtained by a MTIOCGET ioctl system call. The registers are described
in /sys/sundev/tmreg.h (Sun system with TapeMaster controller). If you have a VAX, the file-
name will be slightly different. Sun Microsystems supplies this file even with binary-only distributions.
