bdb_fetch(): "fetch" a record.
INPUT: bdb_handle : valid handle returned from bdb_open() or
bdb_open_more()
ix : pointer to index data
ixnum : which index are we using for the find
ixlen : size in bytes of index specified data
dta : pointer to memory in which to return
the data portion of the found record
dtalen : size in bytes of the memory pointed to
by dta
OUTPUT: RETURN : success : 0 : found exact match. next key
is not exact match.
1 : found exact match. next key
is also exact match.
2 : not found,
here is next
3 : not found, end of db hit,
here is last
99: not found, db empty,
here is nothing
failure : -1 : additional info in bdberr
dta : pointer to the data of the found record
reqdtalen : the size in bytes of the returned record.
if (reqdtalen > dtalen) then only the first
dtalen bytes of the record have been returned
into the memory pointed to by dta.
ixfound : pointer to the full key that was found. ixfound
must point to memory >= to the size of the ix
as was initially speicfied when bdb_open() was
called.
rrn : rrn of the record that is being returned.
only defined for RETURN = 0, 1, 2, 3.
bdberr : will be set to provide additional
info on failure. possibilities are:
catastrophic:
BDBERR_FETCH_IX : trouble with ix file
BDBERR_FETCH_DTA : trouble with dta file
BDBERR_MISC : some problem
non catastrophic:
BDBERR_BADARGS : invalid args
