7 * regex.c: Interface to libPCRE (perl compatible regular expressions).
15 * Creates a new 'regex' struct containing the given pattern and a PCRE
16 * compiled regular expression. Also, calls pcre_study because this regex will
17 * most likely be used often (like for every new window and on every relevant
18 * property change of existing windows).
20 * Returns NULL if the pattern could not be compiled into a regular expression
21 * (and ELOGs an appropriate error message).
24 struct regex *regex_new(const char *pattern);
27 * Frees the given regular expression. It must not be used afterwards!
30 void regex_free(struct regex *regex);
33 * Checks if the given regular expression matches the given input and returns
34 * true if it does. In either case, it logs the outcome using LOG(), so it will
35 * be visible without debug logging.
