log a user message from a console app
Synopsis
#include <libaudit.h>
int audit_log_user_comm_message(int audit_fd,
int type,
const char *message,
const char *comm,
const char *hostname,
const char *addr,
const char *tty,
int result);Description
This function will log a message to the audit system using a predefined message format. This function should be used by all non-ELF console apps that do not manipulate accounts, groups, or need to log execution of a script. An example would be a Python script recording an event. The function parameters are as follows:
audit_fd - The fd returned by audit_open type - type of message, ex: AUDIT_USYS_CONFIG, AUDIT_USER_LOGIN message - the message text being sent comm - the task command name from /proc/self/comm, NULL if unknown hostname - the hostname if known, NULL if unknown addr - The network address of the user, NULL if unknown tty - The tty of the user, if NULL will attempt to figure out result - 1 is "success" and 0 is "failed"
The kernel task command name is limited to 15 bytes because TASK_COMM_LEN is 16 bytes including the terminating null byte. A non-NULL comm value longer than 15 bytes is truncated to 15 bytes and a warning is logged.
Return Value
It returns the sequence number which is > 0 on success or <= 0 on error.
Errors
This function returns -1 on failure. Examine errno for more info.
