Basically (ignoring the case of multiple threads in the following example): You set a static variable which remebers when you entered |malloc()| (and clear it when you leave the function). If you enter |malloc()| and the variable is already set then you're likely hitting the case of a |malloc()| call interupted by a signal handler (note that this may be nested infinitly (for example if someone bombs a process with various signals)). ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.mainz at nrubsig.org \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 3992797 (;O/ \/ \O;)
