Function Documentation

static char* get_hfblock	(	str *	uri,
		struct hdr_field *	hf,
		int *	l,
		struct socket_info **	send_sock
	)			`[inline, static]`

Convert a header field block to char array.

Convert a header field block to char array, allocated in pkg_mem.

Parameters:

	uri	SIP URI
	hf	header field
	l
	send_sock	socket information

Returns:: new allocated char array on success, zero otherwise

		str *	method,
		str *	body,
		int *	cseq,
		str *	callid
	)			`[static, read]`

Check if the request pushed via MI is correctly formed.

Check if the request pushed via MI is correctly formed. Test if necessary SIP header fileds are included, could be parsed and the CSEQ is correct.

Parameters:

	msg	SIP message
	method	SIP method
	body	SIP body
	cseq	SIP CSEQ value
	callid	SIP callid, optional

Returns:: zero on success, or a mi_root with an error message included otherwise
