Zdenek Kabelac	511a5f3ad8	Add test for memory allocation failures ... Replace asserts with test for failing memory allocation. Add at least stack traces. Index counter starts from 1 (0 reserved for error), so replacing fingerprint.	2012-02-10 13:49:29 +00:00

Zdenek Kabelac	303923fbf1	Use const char* const * for dm_regex_create() ... Change API interface to accept even completely const array patterns. This should present no change for libdm users and allows to pass pattern arrays without cast to const char **.	2010-12-20 13:23:11 +00:00
