AUDIT\_REQUEST\_SIGNAL\_INFO(3) Linux Audit API AUDIT\_REQUEST\_SIGNAL\_INFO(3)

# [NAME](#NAME)

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

# [SYNOPSIS](#SYNOPSIS)

**#include <libaudit.h>**

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

# [DESCRIPTION](#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](#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.
