We have Sun OS 5.9 we are doing a backup process (ProC program) that uses the function...

fprintf(fp,"%s;%s;%s;%s;%s;%ld;%ld;%ld;%ld;%s;%s;%s;%d;%s;%s;%s;%ld;%s;%s;%s;%ld;%ld;%s;%ld;%s;%ld;% s;%s;%c%c",x_contrno, x_subno, x_b_subno,x_transdate,x_last_traffic_date,BillAmt_s, x_billamount_int, x_duration
, x_act_duration,x_third_party_no, x_call_type,x_tariffclass,x_party_flag,x_chargetype,x_vol_group,x_billcode,x_no_packets,v_SUBSCR_TYP E.arr,v_AREA.arr,v_TARIFF_GROUP.arr,file_id0,d_GROSS_AMOUNT,v_UPDATED,d_RATE_POS
,v_DISC_TYPE.arr,d_OTHER_AMOUNT,v_OTHER_GROUP.arr,v_TARIFF_PROFILE.arr,0x0D,0x0A);

and fp is declared such that

FILE *fp (fp is pointer to file)

MY problem is that I can't exceed 2GB as file size ......

What are the options availabe to increase the file size to be unlimited............?

and I need to know if this file size depends on the filesystem itself...

What kind of filesystem is it? If it is VxFS (Veritas file system) you can set the largefiles flag in /etc/vfstab and reboot. If you want to increase it on the fly there is a command, I believe it is called fsadm, which can do that. Check your Veritas man pages for details, but I know you can do it.

If it is UFS I'm not sure if you can change it once the filesystem has been created.

I have UFS file system...
!!!!!
Please if anybody help I would appreciate that......

Mounting

/homes on /dev/dsk/c1t0d0s6 read/write/setuid/intr/largefiles/xattr/onerror=pani
c/dev=1d8000e on Wed Feb 11 20:59:31 2004

means the file system supported large files ....

relating the C program......

Post the output from:
isainfo -b
isainfo -v
isainfo -kv
All of these need to say "64". Read the man page for your compiler. Are you putting it 64-bit mode? If not then you must be using the stuff mentioned in "man lfcompile".

To see if the filesystem supports largefiles --- try it. Use some program that you did not write to attempt to create a largefile. "man largefile" will list the os commands that are large file aware.

[Billtest]tabs:/homes/tabs>isainfo -b
64
[Billtest]tabs:/homes/tabs>isainfo -v
64-bit sparcv9 applications
32-bit sparc applications
[Billtest]tabs:/homes/tabs>isainfo -kv
64-bit sparcv9 kernel modules
[Billtest]tabs:/homes/tabs>

Please if you help me in an axample (small C program write to file more than 2GB) using fprintf or fwrite ?

as it is an important issue here to backup local calls details table.....
