Function Documentation

struct proxy_l* add_proxy	(	str *	name,
		unsigned short	port,
		unsigned short	proto
	)			`[read]`

Add a proxy to beginning of the global list, if not already there.

Parameters:

	name	proxy name
	port	proxy port
	proto	proxy protocol

Returns:: pointer to the new created proxy, or zero on error

static struct proxy_l* find_proxy	(	str *	name,
		unsigned short	port,
		int	proto
	)			`[static, read]`

Searches for a certan proxy.

Search for the proxy named 'name', on port 'port' with proto 'proto'.

Note:: Use proto==0 for a proto wildcard (this will match any proto)

Parameters:

	name	proxy name
	port	proxy port
	proto	proxy protocol

Returns:: pointer to proxy_l on success or 0 if not found

struct proxy_l* mk_proxy	(	str *	name,
		unsigned short	port,
		unsigned short	proto,
		int	is_sips
	)			`[read]`

Create a new proxy, but don't add it to the global list.

Create a new proxy in private memory, but don't add it to the global list. This also uses SRV for lookup if possible & port==0 (quick hack).

Note:: this is the same as add proxy, but don't add the proxy to the list

Parameters:

	name	proxy hostname
	port	proxy port
	proto	proxy protocol
	is_sips	set to 1 if you use SIPS

Returns:: pointer to the proxy, or zero on error

struct proxy_l* mk_proxy_from_ip	(	struct ip_addr *	ip,
		unsigned short	port,
		unsigned short	proto
	)			`[read]`

Create a new proxy, but don't add it to the global list.

Create a new proxy in private memory, but don't add it to the global list. This also uses SRV for lookup if possible & port==0 (quick hack).

Note:: this is the same as mk_proxy, but get the host as an ip

Parameters:

	ip	proxy name as IP address
	port	proxy port
	proto	proxy protocol

Returns:: pointer to the proxy, or zero on error

struct proxy_l* mk_shm_proxy	(	str *	name,
		unsigned short	port,
		unsigned short	proto,
		int	is_sips
	)			`[read]`

Create a new proxy, but don't add it to the global list.

Create a new proxy in shared memory, but don't add it to the global list. This also uses SRV for lookup if possible & port==0 (quick hack).

Note:: this is the same as add_proxy, but don't add the proxy to the list and also works in shared memory

Parameters:

	name	proxy hostname
	port	proxy port
	proto	proxy protocol
	is_sips	set to 1 if you use SIPS

Returns:: pointer to the proxy, or zero on error
