audit_getloginuid − Get a program’s loginuid value
#include <libaudit.h>
uid_t audit_getloginuid(void);
This function returns the task attribute loginuid.
This function returns the loginuid value if it was set. It will return a −1 if loginuid was unset. However, since uid_t is an unsigned type, you will see the converted value instead of −1.
This function returns −1 on failure. However, in the event of a real error, errno would be set. The function can set errno based on failures of open, read, or strtoul.
audit_setloginuid(3).
