Ignore functions in Valgrind memcheck

Question

Valgrinding a program that uses openldap2's libldap is a chore because of OpenSSL's use of uninitialized memory. There exists a --ignore-fn option, but only for the massif subcomponent of Valgrind. Is there anything similar for memcheck to exclude traces in which certain functions appear?

You can create a suppression file and use it to suppress errors coming from certain sources: http://valgrind.org/docs/manual/manual-core.html#manual-core.suppress
