int parse_params	(	str *	_s,
		pclass_t	_c,
		param_hooks_t *	_h,
		param_t **	_p
	)

Parse parameters.

Parameters:

	_s	string containing parameters, it will be updated to point behind the parameters
	_c	class of parameters
	_h	structure that will be filled with pointer to well known parameters
	_p	linked list of parsed parameters will be stored in the variable _p is pointing to

Returns:

0 on success and negative number on an error
