TP.RD9 - read a 9-channel tape.
Usage:
B:
status = tp.rd9( unit, buffer, bytes );
C:
int tp_rd9(FILE *unit, void *buffer, int bytes );
Where:
- unit
- is an open I/O unit associated with a 9-channel tape.
- buffer
- points to a buffer into which TP.RD9 places the data it
reads.
- bytes
- is the maximum number of bytes of data you want to read.
- status
- is the number of bytes read, if the I/O operation was
successful. If an I/O error occurs, "status"
receives the negative of the major error status. A status
of zero indicates that an EOF (tapemark) was read.
Description:
TP.RD9 reads the requested number of bytes from a 9-channel
tape into the specified buffer.
