Re: [Libguestfs] [EXTERNAL] - Re: LIBGUESTFS mount disk failure
Hi Richard,
Thank you for the response, will set both handler and let you know.
when we try to execute guestfs_mount_local.
Getting below error :
[ 2023-09-19 13:34:05 ] errno: ( 0 ) : mount_local: unknown option 554101136 (this can
happen if a program is compiled against a newer version of libguestfs, then dynamically
linked to an older version)
Setup details :
OS : (PRETTY_NAME="Red Hat Enterprise Linux 8.2 (Ootpa)")
Guesfs.h version : 1.50
Guestfish version : guestfish
1.38.4rhel=8,release=15.module+el8.2.0+5297+222a20af,libvirt
In Below scenario:
1. guestfs_mount_local_run
2. umount /mountpoint
3. Again, while trying to mount, after sleep of 20sec.
Thanks
RR

I can get guestfs_last_error using function_callback and write to log file.
But "event Handling" is not working Also, std::cout and std::cerr still
printing on terminal.
Is there any workaround for Event Handling?
How to completely disable/enable standard output?

In the two programs in that issue, the first program sets an event callback and the second
program sets an error handler. To capture all messages you must set both together.
If you can produce a single, short reproducer which uses both types of handlers and still
prints to stderr, then I can look at that.
Rich.
