Error handling
Unless states otherwise in documentation of a function, all functions return int, which is zero (0) when the function succeeds, and positive number if the function fails. The returned integer is one of the ECG* values described below. Value ECGOTHER means that the error was caused by underlying OS and the real cause can be found by calling cgroup_get_last_errno().
#define	ECGRULESPARSEFAIL   ECGROUPPARSEFAIL
	Legacy definition of ECGRULESPARSEFAIL error code.
