# audit\_request\_signal\_info(3)

Request signal info for the audit system

## NAME

audit\_request\_signal\_info - Request signal info for the audit system

## SYNOPSIS

**#include \<libaudit.h\>**

**int audit\_request\_signal\_info(int***fd);"*

## DESCRIPTION

audit\_request\_signal\_info requests that the kernel send information about the sender of a signal to the audit daemon. The signal info structure is as follows:

```
struct audit_sig_info {
        uid_t           uid;
        pid_t           pid;
        char            ctx[0];
};
```

This function is likely to be used only by audit daemons and shouldn't be called by any other kind of program.

## 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

[**audit\_open**(3)](/audit_open/3.md), [**audit\_get\_reply**(3)](/audit_get_reply/3.md).
