Fw: tape copy

[Odin Explorer - Chpros]

 Hi ,
 I develop my simple tcopy program on C language for Red Hat 7.2 Linux. My tcopy
 program
 working as standard "tcopy /dev/rmt1" on AIX UNIX machine.
 Result of reading seismic SEG_Y tape is:
./tcopy /dev/st0
 tcopy: Tape File 1; Record:  1; Size 3200
 tcopy: Tape File 1; Record:  2; Size 400
 tcopy: Tape File 1; Records: 3 to 2178; Size: 10480
 ************************************************************
 tcopy: Tape File 2; Record:  1; Size 3200
 tcopy: Tape File 2; Record:  2; Size 400
 tcopy: Tape File 2; Records: 3 to 518; Size: 10484
  ************************************************************
 tcopy: The end of tape is reached. Files on tape: 2

 Text of tcopy.c program look at attached file.
 To compile program  should be used command line:
gcc -o tcopy tcopy.c
My tcopy (Tape copy)  program work untrustworthy unlike standard AIX UNIX tcopy
program.
I get received "Read Failed." message very often.
What is  problem?

Best Regards,
Valery Barinov.
