Typedefs
typedef void(*	pm_regexp_name_callback_t) (const pm_string_t *name, void *data)
	This callback is called by pm_regexp_parse() when a named capture group is found.
typedef void(*	pm_regexp_error_callback_t) (const uint8_t *start, const uint8_t *end, const char *message, void *data)
	This callback is called by pm_regexp_parse() when a parse error is found.

Functions
