SIGINT and mysql_close

Hi all,
I have an app, written in C, which uses mysql client to talk to a mysql DB. One
of the requirements is to catch SIGINT and make sure the app shuts down
gracefully - which means I need to call mysql_close() from within the signal
handler. 
When I try to do this, the signal handler seems to enter an infinite loop
(something in mysql_close seems to emit the signal again). Im not entirely clear
whats happening. 
Any suggestions on how to handle this. Is there a graceful way to terminate
mysql connection on SIGINT/SIGQUIT.

Thanks,
Praveen
