AUDIT_ADD_RULE_DATA(3)						  Linux Audit API					    AUDIT_ADD_RULE_DATA(3)

NAME
audit_add_rule_data - Add new audit rule SYNOPSIS
#include <libaudit.h> int audit_add_rule_data (int fd, struct audit_rule_data *rule, int flags, int action); DESCRIPTION
audit_add_rule adds an audit rule previously constructed with audit_rule_fieldpair_data(3) to one of several kernel event filters. The fil- ter is specified by the flags argument. Possible values for flags are: o AUDIT_FILTER_USER - Apply rule to userspace generated messages. o AUDIT_FILTER_TASK - Apply rule at task creation (not syscall). o AUDIT_FILTER_EXIT - Apply rule at syscall exit. o AUDIT_FILTER_TYPE - Apply rule at audit_log_start. The rule's action has two possible values: o AUDIT_NEVER - Do not build context if rule matches. o AUDIT_ALWAYS - Generate audit record if rule matches. RETURN VALUE
The return value is <= 0 on error, otherwise it is the netlink sequence id number. This function can have any error that sendto would encounter. SEE ALSO
