,[ long tag ] ); /* i */
_status_lt (<return_value>) An error occurred (call FILEINFO).
_status_eq (<return_value>) CONTROL was successful.
_status_gt (<return_value>) For magnetic tape, the end of file (EOF) was
encountered while spacing records; for a process
file, the process is not accepting CONTROL
system messages. When device handlers do not
allow the operation, file-system error 2 returns.
Note. CONTROL operations are summarized in Section 5. CONTROL operations used with
the I/O devices are discussed in the Guardian Procedure Calls Reference Manual.
