I believe that I have a bug in my dbm(3X) package. I wrote
a program to store news header Message-I.D.: 's ( I am working on an
alternate news reader). The program goes through articles in different
news groups, locates the message id field, and uses it as a key
to store the value returned from time(2). After the program runs through
all of the articles in the list, all of the articles should be in a
history file. When I run the program again, about 1/3 of the articles
are re-read. The fetch is not finding them in the history file. The
other 2/3 are in the history file and are not re-read. If I run the
program a second time, storing the articles that are re-read, and
a third time, then the articles are finally marked as all read. I wrote
a program to traverse the data base using the example code in the manpage
for dbm(3x) (firstkey().. nextkey...) and it retrieves several keys, but when
I fetch the data for they key it returns a null data pointer.
DATA:
Computer is Symmetric 375
OS is Berkley 4.2 (probably modified by Symmetric)
I looked at /usr/lib/libdbm.a and found it to be 1300 bytes long.
I decide that this was too short so I looked (ar t) in my
/lib/libc.a and found most of the entry points for
ndbm(?). This may be of help.
QUESTIONS:
1. Am "I" doing something wrong?
2. Can this be fixed without source code?
3. Is there a public version of dbm(3x), or equivalent?
