947# basically look for the first lseek command (we do the strings/grep because
948# sometimes the function call is _llseek or something) and steal the 2nd
949# parameter. here is an example:
950# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
951# lseek
952# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin

1154# the whole 'non-interactive' policy, but damnit I want CD support !
1155#
1156# with these cdrom functions we handle all the user interaction and
1157# standardize everything. all you have to do is call cdrom_get_cds()
1158# and when the function returns, you can assume that the cd has been
1159# found at CDROM_ROOT.
1160#
1161# normally the cdrom functions will refer to the cds as 'cd #1', 'cd #2',
1162# etc... if you want to give the cds better names, then just export
1163# the CDROM_NAME_X variables before calling cdrom_get_cds().
1164#
