1.4.10: log_facilityemptyset - Manipulate log facility sets

CALLING SEQUENCE:

#include <evlog.h>

int log_facilityemptyset(
  log_facility_set_t  *set
);

STATUS CODES:

A successful call to log_facilityemptyset() returns a value of zero and a unsuccessful call returns the errno.

EFAULT
The set argument is an invalid pointer.

DESCRIPTION:

The log_facilityemptyset() function initializes the facility set pointed to by the argument set, such that all facilities are excluded.

NOTES:

The _POSIX_LOGGING feature flag is defined to indicate this service is available.

Applications shall call either log_facilityemptyset() or log_facilityfillset() at least once for each object of type log_facilityset_t prior to any other use of that object. If such an object is not initialized in this way, but is nonetheless supplied as an argument to any of the log_facilityaddset(), logfacilitydelset(), log_facilityismember() or log_open() functions, the results are undefined.
