Hello,
I was facing a problem with a functio I wrote, checking if a file exists
withing the fs. When I was debuggin that , I set 2 breakpoints, the first to
the function file_exists and the second to the function call of file_exists
inside the program. I got the following output
**************************** gdb ************************************
Breakpoint 2, main (argc=1, argv=0xbffff1c4) at ddnscli.c:712
712 if(file_exists(lockfile))
(gdb) s
Breakpoint 1, file_exists (fname=0xbffff110 "disabled") at ddnscli.c:689
689 if( (rval = stat( fname, &attribut)) == -1)
(gdb) s
__stat (file=0xbffff070 "\200", buf=0xbffff070) at stat.c:51
51 stat.c: Datei oder Verzeichnis nicht gefunden.
in stat.c
(gdb) bt full
#0 __stat (file=0xbffff070 "\200", buf=0xbffff070) at stat.c:51
No locals.
#1 0x0804a56b in file_exists (fname=0xbffff110 "disabled") at ddnscli.c:689
attribut = {st_dev = 128, __pad1 = 34760, st_ino = 7, st_mode = 53,
st_nlink = 1075277812, st_uid = 1075283840, st_gid = 134522768,
st_rdev = 4615200421588234412, __pad2 = 34688, st_size = 40,
st_blksize = 1075277812, st_blocks = 1073835200, st_atime = 134522768,
st_atimensec = 3221221564, st_mtime = 1074560382, st_mtimensec = 40,
st_ctime = 1075277812, st_ctimensec = 3221221592, __unused4 = 1074559989,
__unused5 = 40}
rval = 1075277812
*************************************************************************************
__stat (file=0xbffff070 "\200", buf=0xbffff070) at stat.c:51
both arguments of stat hold the same address. file should be AFAIK
fname=0xbffff110.
I isolated the function to a test_program and it works fine there.
Any ideas?
Regards,
Oliver
