It signifies the record's type.

in audit.h, things are name spaced so they don't collide with defines 
elsewhere. They all have an AUDIT_ prefix. So, if you wanted to mape them, 
AUDIT_USER_LOGIN would be printed as USER_LOGIN. There is a function that 
does this mapping from number to string and another string to number. From 
libaudit.h:

extern int        audit_name_to_msg_type(const char *msg_type);
extern const char *audit_msg_type_to_name(int msg_type);


You should not have to write this function yourself since the audit libraries 
have conversion functions.
