NAME

       sip_sendmsg - send an outbound SIP message to the SIP stack for processing

SYNOPSIS

       cc [ flag ... ] file ... -lsip [ library ... ]
       #include <sip.h>

       int sip_sendmsg(sip_conn_object_t obj, sip_msg_t sip_msg,
	    sip_dialog_t dialog, uint32_t flags);

DESCRIPTION

       The  sip_sendmsg()  function is used to send an outbound SIP message sip_msg to the SIP stack on its way to the peer. The connection object
       for the SIP message is passed as obj. The caller also provides the dialog associated with the message, if one exists. The value of flags is
       the result of ORing the following, as required:

       SIP_SEND_STATEFUL     Send  the	request  or response statefully. This results in the stack creating and maintaining a transaction for this
			     request/response. If this flag is not set transactions are not created for the request/response.

       SIP_DIALOG_ON_FORK    When this flag is set, the stack may create multiple dialogs for a dialog completing response. This may result due to
			     forking of the dialog creating request. If this flag is not set, the first response to a dialog creating request cre-
			     ates a dialog, but subsequent ones do not. It is only meaningful if the stack is configured to maintain dialogs.

RETURN VALUES

       The sip_sendmsg() function returns 0 on success and the appropriate error on failure.

       The value of errno is not changed by these calls in the event of an error.

ERRORS

       The sip_sendmsg() function can return one of the following errors on failure:

       EINVAL	 If a message is being statefully sent and the branchid in the VIA header does not conform to RFC  3261  or  when  accessing  CSEQ
		 header while creating a transaction.

       ENOENT	 If a message is being statefully sent, error getting the CSEQ header while creating a transaction.

       EPROTO	 If a message is being statefully sent, error getting the CSEQ value while creating a transaction.

       ENOMEM	 If  the  message  is  being  statefully  sent, error allocating memory for creating or adding a transaction or during transaction
		 related processing.

NAME

       sip_delete_start_line, sip_delete_header, sip_delete_header_by_name, sip_delete_value - delete a SIP header or a header value

SYNOPSIS

       cc [ flag ... ] file ... -lsip [ library ... ]
       #include <sip.h>

       int sip_delete_start_line(sip_msg_t sip_msg);

       int sip_delete_header(sip_msg_t sip_header);

       int sip_delete_header_by_name(sip_msg_t msg,
	    char *header_name);

       int sip_delete_value(sip_header_t sip_header,
	    sip_header_value_t sip_header_value);

DESCRIPTION

       The sip_delete_start_line() function deletes the start line, a request or a response line, from the SIP message sip_msg.

       The sip_delete_header() function deletes the SIP header specified by sip_header from the associated SIP message sip_msg.

       The  sip_delete_header_by_name()  function deletes the SIP header name specified by header_name (long or compact form) from the SIP message
       sip_msg.

       The sip_delete_value() deletes the SIP header value specified by sip_header_value from the SIP header sip_header.

       When a SIP header or value is deleted, the corresponding header or value is marked as deleted.  Lookups ignore headers or values  that  are
       marked as deleted.

RETURN VALUES

       These functions return 0 on success and the appropriate error on failure.

       The value of errno is not changed by these calls in the event of an error.

ERRORS

       On failure, the returned error could be one of the following:

       EINVAL	 If any of the required input is NULL.

		 If the header or value to be deleted does not exist.

		 If the header or value to be deleted has already been deleted.

       EPERM	 If the SIP message cannot be modified.
