Hi,
I am (still) using imap2004-g and I am developing a multi-thread mail
client on top of c-client.
I am having a threading issue with env_init(). In my understanding,
c-client is supposed to be thread safe but might be calling some
non-thread safe c library functions. I did took care of the non-tread
safe c calls and there are not the problem.
My problem is that my application can have several threads (all
connected to different IMAP server) which do a mail_sub potentially at
the same time which cause c-client to generate a fatal error and abort.
The threading issue is with the global variable myUserName (and
potentially myHomeDir) which the env_init() function use to detect if it
has already been called.
First I am not sure why c-client want to get access to the user home
directory, it's apparently to cache on disk some information about
subscribed folders, but is it really necessary? can I prevent that?
About the threading issue, maybe I can force the env_init function to
get called when I initialize the c-client's drivers before I spin out
the other threads or maybe I should just set myUserName and myHomeDir
using env_parameters(SET_USERNAME, xxx) and parameters(SET_HOMEDIR,
xxx). I am not sure what's the best solution!
Any suggestion?
Thanks for your help,
Jean-François Ducarroz
