Functions

• int fix_cfg_file (void)

  Update cfg_file variable to contain full pathname.
  

• int parse_phostport (char *s, char **host, int *hlen, int *port, int *proto)

  get protocol host and port from a string representation.
  

• static struct name_lst * parse_phostport_mh (char *s, char **host, int *hlen, int *port, int *proto)

  get protocol host, port and MH addresses list from a string representation.
  

Variables

• int log_stderr = 0

  non-zero if logging to stderr instead to the syslog
  

• int process_no = 0

  my_pid(), process_no are from pt.h but we cannot #include it here because of circular dependencies

Function Documentation

int fix_cfg_file

(

void

)

The function updates the value of cfg_file global variable to contain full absolute pathname to the main configuration file of SER. The function uses CFG_FILE macro to determine the default path to the configuration file if the user did not specify one using the command line option. If cfg_file contains an absolute pathname then it is used unmodified, if it contains a relative pathanme than the value returned by getcwd function will be added at the beginning. This function must be run before SER changes its current working directory to / (in daemon mode).

Returns:

Zero on success, negative number on error.

int parse_phostport	(	char *	s,
		char **	host,
		int *	hlen,
		int *	port,
		int *	proto
	)

parses [proto:]host[:port] or [proto:](host_1, host_2, ... host_n)[:port] where proto= udp|tcp|tls|sctp

Parameters:

	s	- string (like above)
	host	- will be filled with the host part Note: for multi-homing it wil contain all the addresses (e.g.: "sctp:(1.2.3.4, 5.6.7.8)" => host="(1.2.3.4, 5.6.7.8)")
	hlen	- will be filled with the length of the host part.
	port	- will be filled with the port if present or 0 if it's not.
	proto	- will be filled with the protocol if present or PROTO_NONE if it's not.

Returns:

fills proto, port, host and returns 0 on success and -1 on failure.

static struct name_lst* parse_phostport_mh	(	char *	s,
		char **	host,
		int *	hlen,
		int *	port,
		int *	proto
	)			[static, read]

parses [proto:]host[:port] or [proto:](host_1, host_2, ... host_n)[:port] where proto= udp|tcp|tls|sctp

Parameters:

	s	- string (like above)
	host	- will be filled with the host part Note: for multi-homing it wil contain all the addresses (e.g.: "sctp:(1.2.3.4, 5.6.7.8)" => host="(1.2.3.4, 5.6.7.8)")
	hlen	- will be filled with the length of the host part.
	port	- will be filled with the port if present or 0 if it's not.
	proto	- will be filled with the protocol if present or PROTO_NONE if it's not.

Returns:

fills proto, port, host and returns list of addresses on success (pkg malloc'ed) and 0 on failure
