Hi,
We are trying to run dbx on a core file for which we have the original executable and libs, but not the source / object tree. We have recompiled the objects from the original source, but dbx complains that they were compiled at a different time, and refuses to read them:

dup
DUP(2) BSD System Calls Manual DUP(2)NAME
dup, dup2 -- duplicate an existing file descriptor
SYNOPSIS
#include <unistd.h>
int
dup(int oldd);
int
dup2(int oldd, int newd);
DESCRIPTION
Dup() duplicates an existing object descriptor and returns its value to the calling process (newd = dup(oldd)). The argument oldd is a small
non-negative integer index in the per-process descriptor table. The value must be less than the size of the table, which is returned by
getdtablesize(2). The new descriptor returned by the call is the lowest numbered descriptor currently not in use by the process.
The object referenced by the descriptor does not distinguish between oldd and newd in any way. Thus if newd and oldd are duplicate refer-
ences to an open file, read(2), write(2) and lseek(2) calls all move a single pointer into the file, and append mode, non-blocking I/O and
asynchronous I/O options are shared between the references. If a separate pointer into the file is desired, a different object reference to
the file must be obtained by issuing an additional open(2) call. The close-on-exec flag on the new file descriptor is unset.
In dup2(), the value of the new descriptor newd is specified. If this descriptor is already in use, the descriptor is first deallocated as
if a close(2) call had been done first.
RETURN VALUES
The value -1 is returned if an error occurs in either call. The external variable errno indicates the cause of the error.
ERRORS
Dup() and dup2() fail if:
[EBADF] Oldd or newd is not a valid active descriptor
[EMFILE] Too many descriptors are active.
SEE ALSO accept(2), open(2), close(2), fcntl(2), pipe(2), socket(2), socketpair(2), getdtablesize(2)STANDARDS
Dup() and dup2() are expected to conform to IEEE Std 1003.1-1988 (``POSIX.1'').
