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. ATTRIBUTES

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. ATTRIBUTES
