As an example, let's consider the function for analyzing a line line of output from a standard UNIX finger service. In each line of finger output the first field contains username, the third field --- tty number (Port ID), and the seventh field contains session ID. The function must return 1 if the three fields match the input user name, port and session IDs.
integer
check_unix(string str, string name, integer pid, string sid)
{
return field(str, 1) == name
&& field(str, 3) == pid
&& field(str, 7) == sid;
}
Next example is a function to analyze a line of output from an SNMP query returning a user name. This function must return 1 if entire input line matches the user name.
integer
check_username(string str, string name, integer pid, string sid)
{
return str == name;
}
