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 speci-
fied 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.SunOS 5.11 Last change: 20 Jan 2007 1
